i'm super-impressed by the strategic decisions that facebook has made that keep them heading higher...but can it really last forever? outside of the status updates, their data is getting stale. who updates their info? who spends time to remove items? that's just not the focus of the site like it used to be. tying in with the social graph was the most important move they made to ensure some sustainability that usually alludes social networks. still, i maintain that a social network can't last forever (unlike a resource like wikipedia which will always be valuable)
