She has participated in many a lip-dub video herself, including one with Julia Allison, the New York party attendee who parlayed a career of writing about nothing for magazines to appearing on the cover of magazines for doing nothing. Allison is not mentioned in her piece, but she is surely present within it; Zuckerberg mentions "Flagpole Sitta," a lip dub performed by the employees of Connected Ventures, the ex-startup of Allison's ex-boyfriend Jakob Lodwick.

Allison dispatched, Zuckerberg moves to targets closer to home, taking on the Camp Cyprus 20, the Internet 20somethings who filmed themselves singing along to "Don't Stop Believin'" at a seaside vacation home in Cyprus right as Wall Street imploded. What she does not mention: That the first person we see in the video is her Facebook coworker Dave Morin; Facebook engineers and designers appear later. Zuckerberg slams them all equally: "You hate them for having so much fun — damn that unbridled, financially secure joy!"

Next target: Revision3, the San Francisco online-video startup best known for recording Diggnation, a podcast by Digg founder Kevin Rose. "They probably won't be recording any more lip dubs any time soon, we hear they laid off a third of their staff this week," Zuckerberg writes. Ouch! She could have added that after reading her article, Revision3 also won't be lending out its production facilities for any more of Zuckerberg's music videos, as it did for "Dontcha," a spoof about the iPhone.

Ah, the smell of burnt bridges. Zuckerberg, in person, comes across as shy and self-effacing. The only hint of bile I ever detected was in a previous video, "Valleyfreude," where she mocks Friendster, an also-ran social network crushed by Facebook, and scoffs at Yahoo for offering Facebook a mere $1 billion in an acquisition offer her brother turned down.

But Randi Zuckerberg has always had her eyes on a bigger stage than the Valley. Even her job at Facebook, running the site's election-related features, has been helpful in this regard, landing her on ABC and other news broadcasts to talk about online get-out-the-vote efforts. Now she's moonlighting for Tina Brown, in the hopes of getting her hooks into New York media circles.

The Daily Beast, an unwieldy, overstaffed website, is an unlikely candidate to emerge from next year's economic wreckage. But that won't matter to Zuckerberg: She's already perfected the art of stepping over those she can safely discard. Watch out, Facebookers: Do you think she'll forget how you made her take "Valleyfreude" offline?

Something about this arrangement smacks of social climbing. But who's climbing whom? Randi Zuckerberg, one of Facebook's early employees, who helped the site grow to 100 million users? Or a has-been magazine editor, famous in Manhattan but nowhere else, grappling with how to adapt her outrageous spending habits to a far leaner medium, and leaned on her pal Barry Diller to fund and launch the site, rather than trying the entrepreneurial route?

From a Left Coast vantage point, it looks like Brown is trying to attach herself to Zuckerberg's star, not the other way around. Zuckerberg, cleverly, registered her own website, shouldiredorshouldiblue.com. A wise hedge, should Brown's website go down in expensive flames.

Hruska noted that O'Connor's other blog, Ivygate, had called the twins "spoiled bitches that tried to lay one on the invincible Mark Zuckerberg and failed." We don't see the problem with hiring "spoiled bitches" to work at NonSociety — they'll fit right in with Allison! Had Hruska really been cutting, she'd have asked how Julia Allison's latest BFF, Randi Zuckerberg — older sister of the man the Winklevosses accused of stealing ConnectU's code for Facebook — would feel about the hire.

One date per week, a minimum of a hundred minutes of alone time, not in his apartment and definitely not at Facebook.

Chan recently squired Zuckerberg to his sister Randi's wedding. No word on who caught the bouquet, and Facebook insiders are mum about the couple's prospects of an engagement. Come to think of that, perhaps that's a good thing. If dating was this tough, can you imagine working out the prenup?

Previously:

• A is for Adelson, who cofounded Digg


• B is for Botha, who sold YouTube big


• F is for Fitzpatrick, and "hookers and blow"


• L is for Levchin, who never goes slow


• P is for Parker, the Valley's bad boy


• R is for Rose, who made Digg his toy


• T is for Twitter, which turned blogging small

OMG. I just got invited to the Facebook Prom!!!! No, not by @randijayne, although I'm sure she's going to be jealous of my superhot date ;)

Update: Julia Allison has posted another photo of herself with Zuckerberg. Has no one ever told her that only the bride wears white?

Attendees include fellow Facebooker Meagan Marks as well as Zuckerberg's sisters. What about Julia Allison, the New York Web personality who tagged along for an '80s-themed photo shoot with Zuckerberg? She's been known to attend the opening of an email, and Zuckerberg's bachelorette is considerably more momentous. Allison's also bringing sidekick Meghan Asha Parikh, the Silicon Valley heiress, and that annoyingly vapid handbag designer whose name we forget. (Surprisingly, Allison didn't leak her own social calendar to us this time, though she confirms by IM that she's "looking forward to the adorable, ineffable, indefatigable Randi's bachelorette party.")

As for Mark, Randi's younger brother? The Facebook CEO is not invited, as he is (a) a dude and (b) no fun at parties. He is, however, going to Tworetzky's bachelor party in New York. More on that as we get the details. (If you have them, send it in.)

I was on the verge of deleting my Facebook profile, except that as a Gawker Median, I have to have one per company policy. (Well, that, and Facebook's resident chanteuse Randi "Jayne" Zuckerberg left a note on my wall — air kisses!) I settled for deleting all but the basic apps. Just don't tell Mashable's Pete Cashmore the sky is falling. He seems like such a sensitive lad. (Photo by tomnono)

While it looks like comely lifecaster Justine Ezarik, better known as iJustine, who's head over heels for her VC, she's merely lipsynching. The real siren of the piece is Randi Jayne (née Zuckerberg, and yes, she's the Facebook guy's sister) who sings the sultry lyrics. Jayne's fiancé is a VC with Shasta Ventures who served, she says, as her inspiration. Even if this clip, produced by Kevin Rose's Revision3, doesn't approach the level of popularity reached by "Valleyfreude" or the iPhone parody, it's sure to inspire at least one new Valley pickup line: "You can sit on my board anytime."
