Riley told the Daily Mail that she "fell in love with Elon because of our mutual love of physics." Perhaps it was "physiques." Those British accents are tricky. Justine Musk's comment on the 23-year-old Riley, in her LiveJournal: "She is not blonde, and I do find this refreshing."

Gossip column Page Six spotted Tequila "hooking up" with Justin Long, best known for his role as a Mac in Apple commercials, at a Vegas nightclub on Halloween. Will the Mac preference stick? Who knows, but according the a New York Post spy, Long reportedly "asked her [Tequila] to straddle him while making out." What would John Hodgman have to say about this?

Which well-educated Hollywood C-lister has gotten quite the reputation for chasing tail at media and dot-com parties on both coasts in addition to the usual entertainment industry circuit? This has been going on for a while, but it’s only recently begun to turn him into a punchline. And trust me, this fellow should know already that you don’t want to be a punchline among people who write them for a living. Not to mention the fact that gossip about his left-of-center bedroom interests is starting to get out.

Show off your algorithms in the comments. Include this curiosity: Why would a supposedly "well-educated" actor try to pick up women at tech parties?

Hinze, the host of Project Runway Australia, was first spotted on Clark's $100 million megayacht, the Athena, two years ago, while Clark was wrapping up a $125 million divorce settlement with ex-wife Nancy Rutter, a former Forbes reporter, PEHub notes. Small world: Hinze will be YouTube founder Chad Hurley's stepmother-in-law. He's married to Clark's daughter Kathy.

Reporters tend to focus on Bram's potential Asperger's more that he does. He has never used it as an excuse, but used insight about it to understand himself and improve his communication skills. I've known Bram for 12 years and have worked on an off with Autistic spectrum children for 19 years. It was *me* who suggested to him that he might have it after knowing him for about 5 years. It is not a suggestion that I have made often or carelessly even though I have 100's of friend who are Bay Area tech geeks. Bram focuses on his individual strengths and challenges and works tirelessly to improve his communications and relationships with others. Having insight into Aspergers helped him immensely with this effort! He's honest about it because he's willing to be *humble* about not being good at somethings! Not as an excuse. I know very few people of *any* type who are as honest with themselves and others about their own shortcomings or who work as diligently to improve themselves as Bram. Over the last decade I have seen his interpersonal skills grow by leaps and bounds. We haven't sought a formal diagnosis, because we have nothing to prove and he has the support of his friends and family to continue working on perfecting some of the social and communication skills that don't come naturally to him. Despite his sometimes blunt comments and an inability to sugar coat his opinions... he is kind, caring, and down-to-earth. He's a loving playful dad, kind husband, friendly with neighbors, quick to admit his own faults (though not artificially humble about his few great strengths) I wish you would stop harping on those dumb stories... he just wrote them as a yung 'un to attract former goth girls like me ;) They were fiction.. duh! Let's see what we could deduce about *YOU* from *YOUR* porn collection! -Jenna Cohen

But confronted by Mashable about his relationship collection, Alsop freely fessed up: "In his mid-50s, Alsop reaches out to young attractive women and asks if he can be their friend. Many say yes. Alsop says he's an old guy and it makes him feel as if he's got something going on. There's no downside for Alsop. Some may think it's weird, but it doesn't change anything for him."

In case you had any doubts on how free-thinking the Bay Area is on such matters, Robin Wolaner, Alsop's "No. 1 girlfriend" and the CEO of social network TeeBeeDee, supports her man's Facebook habit. Even though, in the same Mashable article, she recommends against accepting friend requests from people you don't really know. Like, say, her 50something venture-capitalist boyfriend.

Alsop hastened to clarify to partygoers that Wolaner is his "no. 1 girlfriend." Why the enumeration? He still has a habit of picking up other women. I mean that literally. I saw him pick a blonde girl off the floor and give her a full-body hug at the party. That's leverage, of some kind or another. I took one of Stewart's sausages to give to the host at my next party.

The previous evening, the Berliner Kurier reports, Wales dined with Celia von Bismarck, shown here, a dilettante magazine editor and think-tanker. (She hates "boring society ladies," according to Vanity Fair, so she and Wales must have self-loathing in common.) No mention of Wales's current fling, Andrea Weckerle, who's said to be on the outs with him after rumors circulated that he sent around racy photos of Weckerle without her knowledge.

On MySpace's Data Availability, a feature which lets MySpace users link their profiles to other services like Twitter, versus Google's similar Friend Connect, he wrote:

MySpace is taking a much more interesting approach than Google.

In an early post about MySpace Music, Arrington gushed:

Music almost certainly plays a part of MySpace’s continued dominance of Facebook.

About MySpace friend-in-chief Tom Anderson's hacking back in the 1980s, Arrington dutifully wrote:

Frankly, my opinion of Tom Anderson just rose significantly.

A week before MySpace Music launched, Arrington quit playing games and just posted free ads for the service. None of that approached the review Arrington gave MySpace Music the morning it launched.

MySpace has done something incredible at a big picture level: they’ve created both a compelling music experience for users as well as a realistic, long term business model for labels and artists in a world where recorded music moves towards free. Depth of catalog and usability is far beyond what other free streaming services like Last.fm and iMeem currently offer. And when it comes to listening to music, the pop out player, pictured above, is excellent. It’s a great resource for users, and it’s likely to become the center of the revenue ecosystem for artists, particularly unsigned artists starting to make a name for themselves. Indie labels are in a great position, too. A lot of positive press is rolling in around this launch, and it’s much deserved.

"We talked and talked and talked and talked and paid no attention to anybody else. I started asking him a whole bunch of questions about his business, not expecting to understand any of it. He's a great teacher, and we couldn't stop talking," Buffett told the newspaper. "We were sort of ignoring all these important people, and Bill's father finally said, gently, that he'd prefer that we join in a little more." Then the conversation turned to sex and computers.

As the night wore on — Gates's helicopter had to fly before it got dark, and he let it go — Gates and Buffett grew more and more fascinated with each other. Buffett asked Gates about IBM and Gates told him to buy stock in Microsoft and Intel. Then, per the rules of the buddy-comedy genre, Gates objectified a woman. (The idea being, of course, to share a sexual course of thought without crossing any societal norms.) Says Buffett: "Bill started trying to convince me to get a computer."

I said I don't know what it's going to do for me. I don't care how my stock portfolio is doing every five minutes. And I can do my income taxes in my head. Gates said he would pick out the best-looking gal at Microsoft and send her to teach me how to use the computer. He would make it totally painless and pleasant. I told him, 'You've made me an offer I almost can't refuse, but I will refuse it.

Levchin's Slide promotes the practice of sharing every precious and not-so-precious moment with the world at large, and that his company has massive amounts of Facebook user data at its disposal thanks to the popularity of the company's Facebook applications. Yes, the rich are different than you and I: They don't buy into the crap they sell us.

We're told Dudeck leaked Arrington not only the MySpace Music screenshots, but also tipped him to a story about MySpace friend-in-chief Tom Anderson's brush with the FBI as a hacker in the 1980s. The article served to burnish Anderson's rather questionable geek credentials.

MySpace has helped Arrington's business in other ways besides feeding him stories. The News Corp.-owned social network was a major sponsor of the recent TechCrunch50 conference.

Arrington has no issue bragging privately about his relationship with Dudeck. And Dudeck, our source says, has "no issues to sleeping with key influencers." Before Arrington, we hear, the rumor was Dudeck dated MySpace CEO Chris DeWolfe.

But don't believe us — let's go to the tape. Check out this clip of DeWolfe and Dudeck together at the Sundance Film Festival earlier this year, caught by Kara Swisher for AllThingsD. The way Dudeck leans in to DeWolfe to stay warm tells you more than any of our anonymous sources.

Kara's quippy response — "You don't have to love me" — reminds me of an anecdote my boss once related about Dudeck. The flirtatious MySpace flack accosted him at a conference last year and said, "We really need to work on our relationship." Sorry, Dani — Owen doesn't swing that way.

Problem: You wake up in bed with someone, and you have no recollection of the night before — including his/her name.
Solution: Go with Michael or Elizabeth! According to admissions statistics, those have been the most popular names for the last 2 years

Problem: She goes dry.
Solution: Do not just keep thrusting, didn’t you learn about friction in physics class?

Problem: You left your iTunes on shuffle and Zelda music came on.
Solution: Do not stop kissing, and ask the girl, “how far do you want to go?” “Err, we can go to base 3.14,” is probably how you should respond.

Problem: You haven’t had sex in months or you’ve never had sex.
Solution: Join the club. I haven’t had sex in months.

See, Paul? Bedroom success for MIT students hasn't changed since your own college days!

Wales has edited Julia Allison's Wikipedia entry — and we all know what that can lead to. Can you add to the sum of all human knowledge with a clever, yet printable, caption? If so, leave it in the comments. The best one will become the post's new headline. Friday's winner: theodp for the "$100 million flipper." (Photo via NonSociety)

More spy photos? Send them in.

Rather than rely on romantic intuition (which Messina all but admits horribly failed him in his last relationship with fellow conference-speaking professional Tara Hunt), the two are now trying to suss out behavioral patterns that might indicate a cooling of interest. How do they do it? With websites that just happen to be eager for publicity.

In tracking everything they do in sites like BaseCamp, BrightKite and Bedpost, the new couple cultivates an early-adopter mystique. Bedpost even allows them to quantitatively analyze the frequency, duration and quality of their naughty bits-mingling. How romantic!

The heart wants what it wants. And in Messina's case? Despite the news hook here being privacy, what his heart really wants is publicity.

Oh, right — because he's not doing any of his jobs well. Sue Gardner, the executive director of Wikipedia's nonprofit parent, the Wikimedia Foundation, has made it clear she's running the show there. And Wikia? Its search engine, the project on which Wales has said he's focusing his energies, has 0.000079 percent of the market.

The common thread: Wales is incapable of sustained attention on anything, or anyone. He once signaled his coupledom by tweeting thanks to an admirer from "Andrea and I." Weckerle has left a coded retort for Wales with this quote from Roy Disney: "It's not hard to make decisions when you know what your values are."

Not as rough a farewell as Rachel Marsden, the conservative Canadian pundit. She auctioned Wales's clothes on eBay after he posted a note on Wikipedia stating that they were no longer an item. Too much trouble, too much effort, for Wales to repeat that kind of drama with Weckerle, we guess.

Breaking up on Twitter? Far more suited to Jimmy's attention span. The only question: When are Wales's backers at Wikia — Bessemer Venture Partners and Amazon.com among them — going to lose interest in him, too?

Leave aside having a fairly public former couple as the face of their business. It's not clear how Hookupdigits believes they'll turn a profit. One of the players behind the site contacted me offering me "rev share" if I "really loved it." A rev share of what? The Google AdSense ads overdecorating the site?

It's a shame that those who would most benefit from Hookupdigits — Internet sex workers and their clients — are exactly the people Hookupdigits can't overtly market to, maybe for fear of being heavily surveilled by law enforcement. What will shut them down won't be police involvement, but lack of a user base. There are still far more people meeting through online dating sites who want to swap real phone numbers before they share anything else — as a sign of mutual trust. Call it old-fashioned. At least if you share your real cell number, you can text your good time, too.

Social networks — the kind Henderson and Waldman work on when they're not using them to flirt — are supposed to expand our worlds. Yet these websites' real effect is to shrink them. Who'd want to start anything with anyone who's not already registered on all the same websites you use? The training time to explain the twee etiquette of Web 2.0 is a barrier to entry more fearsome than any Google or Microsoft might dream up. It can only lead to San Francisco's insider scene becoming literally inbred.

Facebook's most hardcore users — young men pretending not to be looking for sex — can now mark their latest target as theirs in public. But this is no great victory, for women or for dating. Or, for that matter, for them.

For one, it kills their prospects of picking up someone new as a stopgap before their current relationship fails. Unless they can somehow convince their current partner that really, talking about one's relationship in public is only for cads and showoffs, and she's gullible enough to agree.

Even if they do "cancel" their relationship — to use Facebook's lingo — between tagged photos and archived News Feed items, users can no longer count on the one thing that fuels serial monogamy — consensual amnesia. What we can credit Facebook for, maybe, isn't saving romance. But it is saving a little bit of our honesty.

"What's appealing to some may feel a little creepy to others," Newsweek continues. The same goes for the users when signing up for these location-based apps in the first place. What are you asking a friend, exactly, when inviting them to view your movements around a city? It really means you want to see where they are, and who else they may be with. You're not going for friendship so much as mutually assured surveillance.

That users are lying may be painful to friendships, but it's all that's holding the social fabric of these apps together. At Brightkite, glossing over the truth is even built in as a feature: Instead of your precise address being sent as an update, you can opt to have only your city transmitted. Of course, some of your "friends" will figure out immediately that you don't trust them with your whereabouts.

All the more reason not to lean on the "social Web" to manage relationships. The very people most inclined to make use of these apps are the ones who could never pull off fibs with any delicacy in person. Ideally, new services would take people out of the equation even more, and let computers have a go at these problems from start to finish. When I ask my phone where the nearest cafe is, why can't it just know that I mean "the one where my ex isn't currently on a date with someone else, ignoring her and refreshing Twitter"?

And here Mr. Henderson shook my hand and didn't mind at all when I said it was really his longtime companion Tom Coates, part of the Fire Eagle team and old queer hand of the blogosphere, whom I came out to meet. "We're here in my circle of exes," Culver continued. "And I have one to toss back at you," I added.

The rest of the evening is lost in a botched Flip video file sync — no footage for you — and a flurry of text messages wherein I tried to locate the guy getting a handjob in the men's room at the end of the night. No help from Fire Eagle there! Tip me if you know who the lucky jack was? (Photo by Andrew Mager)

According to Woz, the pair may or may not have married under California's century-old confidential civil arrangement, under which no witnesses are necessary and the marriage record is kept private. Only the bride, groom or a court order can pry it loose, so no fear of pesky gossips going to the county clerk's office and pulling a public record. It's fairly popular amongst the Hollywood celebrity set who don't want their nuptials to go out over the wire. Of course, to get said confidential marriage, the parties have to be living together. So either way, Janet and Woz, mazel tov!

...maybe this was the second proposal, with the first one bursting in late 2000?
