FriendFeed lets you connect all your Facebook friends into one place and read all their messages from several of the different social networks they belong to. Say for instance that your friend belongs to Facebook, Twitter, Flickr, del.icio.us, and YouTube. Every time they post an update, photo or video to one of those sites, you'll know about it right away.

Add your own feeds to FriendFeed to. Let's say you want to read your Twitter updates from all your Twitter friends on FriendFeed. Just add your Twitter username to your profile and soon you'll be able to read Twitter here too.
