Keep Track of Your Friends' Shared Items: "FriendFeed is a start-up that wants to solve this issue by letting you enter your usernames from different sites and combining all the data in a single feed that could be easily shared with someone. You can also invite your friends and subscribe to their data. The service makes a lot of sense if you use it from a social network like Facebook, so FriendFeed has a Facebook application."I don't get it. I was able to add one of my blogs as a feed, but I could only see how to add a single blogger feed. I don't see how to delete a FriendFeed account, once you have one it's there forever.
There's probably more than I can see, but if there is more then they have serious usability problem.
