Movable Type's new TrackBack feature is fantastic. [via Blogroots] I think it's exactly what weblogs need, and is what I was getting at when I talked about writing a distributed conversation server. This feature turns MT into a conversation server, and I hope the other tools will follow suit. It's going to automate the process of sharing information at the post level; which will allow new, exciting things to happen in the blogosphere. nice work!
