Facebook’s Open Graph app launch event is underway here in San Francisco, where over 60 new Open Graph websites and apps are demo-ing how they can publish user activity back to Timeline and Ticker . Launch partners include Pinterest, Ticketmaster, Gogobot, Rotten Tomatoes, and many others. Carl Sjogreen, Facebook project manager, also announced that Facebook will now begin approving apps from third-party developers who aren’t partners. The Open Graph platform was first announced at f8 in September. There, music, news reader, and video apps debuted showing how users could share what they listened to, read, or watched. With today’s launch, a wider variety of activity will begin to appear on Tickers, Timelines, and the Facebook news feed. This includes what users have pinned, tickets they’ve bought, trips they’ve planned, and movies they’ve reviewed. Facebook first tried to allow websites to publish back to the news feed years ago with the now infamous Beacon. Because users didn’t quite understand they would be sharing their ecommerce purchases and other activity back to Facebook, some complained their privacy was violated. To prevent a repeat of one of its most notorious missteps, Facebook has created a much clearer opt in permission flow announced earlier today .
