Regarding Google To “Out Open” Facebook On November 5 - beware the fast follower.
Facebook has a pretty nice API, but depending exactly what Google shares it could be possible to build some pretty impressive applications. Imagine knowing the frequency each Gmail contact was emailed… that would make facebook.friends.areFriends look kind of primitive.
Oh, BTW – I was wrong (or more charitably – misguided) about this stuff. Brad was right – making public data portable is the only safe way to go.
