How did Ng get them? Here are his instructions, which involve no real hacking or unauthorized access — just typing in Web addresses. They work because Yahoo allows its users to add their MySpace profiles to their cell phones without checking their credentials; it requires a login, but accepts any login, not the specific user's login.

This points to a flaw in the notion of data portability, a movement which seeks to have personal information shared between social networks and other websites. Data portability was borne out of a wrongheaded assumption: That data needs to be shared. Most consumers, I believe, aren't particularly interested in the concept; they belong to a few social networks at most, and don't find managing their online personas to be a particular challenge. The technophiles of Silicon Valley, however, join every network they hear about, and find retyping their personal information and manually adding friends maddeningly inefficient.

It's all well and good to speed things up, but how far, how fast? The example discovered by Ng just demonstrates the tendency of Web companies to take shortcuts with security. With data portability, we won't just have to worry about how well a particular social network guards their personal data; we'll now have to worry about every partner website it connects with.

Technical experts — every engineer in the Valley considers himself one — will no doubt weigh in with elaborate approaches to assuring security. I'm skeptical that any of them will work. It's a combinatorial problem; not only will the protocols have to be designed to be airtight, but we'll have to trust that each website implements them flawlessly. It only takes one weak link to break the chain. Already, Facebook has cut off Google's connectivity to its profiles in a dispute over whether Google's software is secure enough. Even the fame-seeking likes of Paris Hilton and Lindsay Lohan deserve better.

Part of the issue with Google's Friend Connect is that when users grant access to Google's product, Google might share their information with another application, or some part of it, maybe not all of it, without that user knowing. And part of what makes our system work is that people know exactly who they are sharing all their information with.

Funny thing is, Google claims an employee did talk to Facebook before launching the product. At least, according to Google engineering director David Glazer. No matter, said Zuck. "Google's a big player in the space and they make good things and our goal is to work with them to figure this out." Hear that Larry, Sergey? You guys make good things, so Mr. Zuckerberg will deign to speak with you. After he's done with his round-the-world trot.

Wish Bear / Chris Saad: Formed the DataPortability Working Group in the hopes that his wish — that all websites would share their data — comes true for everyone. Although Saad is not a major player at a big Internet company, pretending to make wishes come true is still a lot of fun.

Tenderheart Bear / Brad Fitzpatrick: Helps everyone show and express their feelings. He helps his fellow Share Bears be as caring as they can be, as the most prominent developer to join the Share Bears. The Share Bears don't have a leader, but as the lead developer of OpenID and other open-source tools at blogging company Six Apart, now the poster boy for Google's OpenSocial platform, Brad Fitzpatrick comes closest to it.

Friend Bear / Dave Recordon: As a close friend of Tenderheart Bear and his replacement as spokesman for open technologies at Six Apart, is a kind and friendly bear. Sometimes he disagrees with his buddy over Google's definition of friendly. Thinks "the social graph" is the meaning of being a good friend.

Love-A-Lot Bear / Ben "Bling" Ling: is a pretty and perky bear who helps spread love and help it along wherever he goes, be it Google or Facebook where he recently defected to to lead its platform program.

Birthday Bear / Joseph Smarr: Plaxo's chief architect hates it when people forget birthdays. That's why he wants you to sync up all of your online identities, so no one misses out on your happy day.

Cheer Bear / Matthew Rothenberg: As the representative for well-liked and fairly open social photo site Flickr, is a very happy and perky bear, who helps everyone be their happiest and cheer up those who are unhappy, like those who work for Google or Facebook.

Grumpy Bear / Marc Canter: Teaches us all that it's okay to be grumpy and vocal about open standards sometimes, but it's also silly to let grumpiness go too far when your own philosophy rarely results in business success. Canter's PeopleAggregator is an example of both supporting open technologies and its irrelevance, the silver lining and the rain cloud.

Bedtime Bear / Marc Canter: So special that he captures the personality of two Share Bears, Canter is a very sleepy bear. He helps everyone get a good night's sleep and have sweet dreams of portable data.

Good Luck Bear / Robert Scoble: Isn't a developer and doesn't work for a major Internet player, but sheer luck has made Scoble an intriguing bit player in the data-portability movement.
