Joey deVilla has a detailed posting Notes from FacebookCamp, Part 1 and promises more, in addtional to the article he’s previously posted on Getting Started with Facebook Application Development; Using the FacebookRestClient Class’ “Event” Methods, Part 1; Using the FacebookRestClient Class’ “Event” Methods, Part 2; and FacebookRestClient’s “Friends” Methods.
we also have Facebook Invades Toronto notes, and David Crow’s chipped in with a couple of links in addition to his very valuable contribution making sure things happened! (I just manage to avoid showing up in the photo, save the blinding light)
Other links about facebook if not the Toronto event are: How to Develop a Hit Facebook App: 29 Essential Tools and Tutorials (from softwaredeveloper) and the just published facebook data store api thoughts.
For a slightly different take see Wired : Slap in the Facebook: It’s Time for Social Networks to Open Up and Web Comic xkcd : Mildly (?) sleazy uses of FaceBook, part 14
and Mark Evans just commented on Facebook’s Booming App Ecosystem
