FriendFeed lets you aggregate content from a number of social media technologies, Twitter, del.icio.us links, blog posts, flickr and many more. FriendFeed also enables you to share comments with friends and colleagues on each shared link and message post. FriendFeed launched last October 2007.
Features that are not entirely obvious when you first sign up with FriendFeed include:
1) The ability to hide those Twitter comments of friends who get too chatty, and mute comments.
2) FriendFeed lets you see the likes and comments of your friends.
3) You can have your FriendFeed comments posted back to Twitter as a @reply Twitter in the comments section of FriendFeed.
4) You can follow what your friends have commented on and liked. This feature is also available for your own profile, you can check out your own comments and likes to see if anyone added to comment threads you have contributed to.
5) This week on Thursday FriendFeed added a new feature, the ability to make rooms, where friends can join and share links, comments and information around a topic, event or idea. The rooms can either be public or private, so it’s a great way to share information with people.
Since Thursday, a lot of people have already been busy creating rooms. Here's a List of Friendfeed Rooms I found:
