Friendfeed

FriendFeed enables you to keep up-to-date on the web pages, photos, videos and music that your friends and family are sharing. It offers a unique way to discover and discuss information among friends. Sign up for FriendFeed, invite some friends, and get a customized feed made up of the content that your friends shared — from news articles to family photos to interesting links and videos. FriendFeed automatically imports shared stuff from sites across the web, so if your friend favorites a video on YouTube, you get a link and a thumbnail of the video in your feed. And if your friend likes a news story on Digg, you get a link in your feed. FriendFeed makes all the sites you already use a little more social.
