I've tried quite a few of them:
4. FriendFeed5. Lifeblob
There are of course many more, but how many can you try ;-) Unfortunately like it happens so often, I liked the original still the best, especially the very first version. FriendFeed has moved on and their future even has become uncertain.
Just for fun I started to work on my own little life stream project. It's inspired very much by FriendFeed, but for some reason I also like the idea of being in control of my own data. I like to keep up with technology and learn something new. It was quite a challenge to come where the app is today. I had to learn some python, deal with a scalable data store and make sure the stream gets automatically refreshed.
