Has Facebook jumped the shark? Most people I know use Facebook dramatically less than they did a year ago. I haven't been on in about a week. But if I am off Twitter for more than a day I suffer acute Tweet withdrawal. Is Facebook going the way of MySpace?

When the Iranian protests exploded it was Twitter's moment. Yes, there were Facebook accounts registering protest. But the 140-character nature of Tweets was the perfect medium for protesters to place busts of information, for watchers to post notes of solidarity and for serious link love. It didn't help that cable news inexplicably took the weekend off, delivering canned programming as Tehran burned. Clearly Twitter is at the zenith of its influence, but does that entail that Facebook is in decline? P.S. You can follow us at @awearnessblog.
