Interesting. Certain Facebook apps (ahem, Farmville) are sharing user info. Maybe that big Jobs-Zuckerberg sit down two weeks ago was a scolding about privacy and user experience? Probably not. In any event the sharing goes against Facebook's own rules.
The report arrives this evening thanks to reporting done over at the Wall Street Journal. In their report, we learn that "tens of millions" of users could be affected, mostly thanks to popular apps created by Facebook games mega developer Zynga. Yes, virtual farmers, this includes your precious Farmville app!
The shared info includes Facebook user IDs, which advertisers and other tracking firms can use to look up user's names and other info on the social network. Oh, and even if you didn't use Farmville or Texas Hold'em, you are still vulnerable, as the breach allows third parties to view the friend lists of affected users and get your information that way. Swell!
