San Francisco - Online social network Facebook has introduced Facebook Connect, which allows outside websites and applications to share data back and forth. The company launched the new feature with 24 partners, including Digg, Movable Type creators Six Apart and Citysearch. The feature allows, for instance, Facebook users to sign in to Digg with their Facebook account authentication, and to have news stories they select via Digg, or comments they leave on Movable Type blogs to show up in their Facebook news feeds.
