Abstract:

Google is no longer the only hub for content discovery. The statusphere is introducing new channels that now serve as our attention dashboards and it's the collection of streams of consciousness from those we choose to follow. Collecta, Twitter Search, Facebook News Feeds, FriendFeed, etc., serve as the gateways to insight and enlightenment.
