soon we will be able to mine the realtime social space for memes and meme likes. sounds valuable.
facebook hasn't delivered. years ago i was sold on this service - i envisioned a future where i could find a doctor via my social network, or collaborate with a team member from within facebook on a document, or play a realtime game with a friend.
the only thing it seems to be good at is spreading wall spam and obscuring content. lets start with the ability to review wall posts by date instead of the endless scroll of stupidity.
I'd rather see that approach than a no entry, shut down developers approach. Admittedly Facebook offers a lot more than Twitter to justify such a cost, but Twitter seems like somewhere developers want to be too. Paid usage API sounds like a good idea to me.
