Web 2.0 Tools

I looked at Blogniscient which was in the same vein as Bloglines, which I already use. It seems like a good place to go to find new and interesting stuff. Not necessarily a good place if you are looking for something specific. I very much enjoyed that they have their own icons (or are they avatars?) for different catergories of blogs. For the political blogs they have them as red or blue for left or right wing content.
