So now "Fan" pages work essentially like Twitter accounts in terms of letting people follow and receive updates. I wonder what they'll do for normal profiles, where you can't look at a person's feed without their accepting. If they figure out a nice solution, then they may have done away with my attention-whoring friends' need for services like Identi.ca, which they use currently to push both to a private profile and to a public Twitter account.
If there's one thing I can say for certain, it's that you're not going to beat Twitter (or any other dead-simple niche service) by trying to be everything to everyone. I am certainly painting in broad strokes here, but this feels a little Microsoft-y to me.
