Blogroots has a new look and some new features. I'm most excited about the potential of Blogpopuli, a TrackBack-powered post aggregator. Basically it's a way of asking weblog authors who post about weblogs to let Blogroots know when they do. In return, Blogpopuli posts an excerpt and a link directly to that post. TrackBack is built into Movable Type, but if someone isn't using that they can still participate with the ping form. We've also put some systems in place for adding resources and reviewing them. It's pretty bare in there right now, because we need to spend some time describing and reviewing tools. But I think it will be very valuable, especially for people new to the weblog world. I see it as a way for more experienced weblog authors to share some of their knowledge of the tools and resources with others.
