I really like the new, cleaner Facebook layout. The older layout causes a great deal more confusion and management difficulty. Emphasizing the activity feeds really moves it closer to solving the difficult problem of centralizing my web activities; FriendFeed accomplishes some of this but feels far less polished. Finding various tools seems easier because of this redesign, though occasionally it still hangs up on me. As it opens up more, though, it’s poised to really take over the world, I think. At least mine, anyway.

UPDATE: Is it just me, or does the new design not really work properly in Firefox?
