Facebook creating a new mobile app platform? I doubt they are capable of producing of high enough quality software to serve as a platform - their iPhone app is the buggiest app I have ever used on the iPhone (constant crashes, stuck interface elements, mismatch between pictures and their thumbnails), and their web site is likely the buggiest web site (duplicate items in news feed, missing items, the message counter is never correct). Basically, on Facebook nothing ever works right. I don't see a lot of people rushing to discard their iOS apps in favor of that.
