Facebook is adding some Twitter-like features. Now the Search is being overhauled.
A second shot at Twitter in two days (first at Berman Post: Facebook Buys FriendFeed)?
"New users to Facebook (and probably some existing users, but not all of them yet) are getting a new search experience in Facebook starting Monday. The new interface for search makes it possible to see all public results from Facebook users (the Everyone filter), or just results from your friends. Or, as before, only Events, Groups, or Applications.
The Everyone filter is the key new feature. It lets Facebook users monitor the entire network for news and updates on big topics, the same way Twitter was consumed for information coming from Iran after the recent election.
Like Twitter Search, the Facebook search result page alerts you when new results come in that match your query, but it doesn't update the whole page until you ask. This is arguably the best way to keep people up to date without overwhelming them."
