I won’t pretend to know too much about these programs, but I will say this — the business development divisions of Google, Myspace, and Facebook are going to be working overtime recruiting partners for the next few months. I don’t anticipate all three of these initiatives will gain traction (unless all the major web portals choose to implement all three APIs), so the race is on to close deals with highly trafficked websites on the web — Myspace has a clear lead early on as a result of their announced data sharing deals with Yahoo, Ebay, and Twitter.
