TweepML is really cool

I love to use friend's OPML files as a way to pre-populate different RSS readers like NetVibes.  It is a lazy way for me to build a great dashboard of content without having to do all of the work.  Marcelo Calbucci's new Twitter service, TweepML, is a similar concept.  I like the fact that I can follow pre-packaged lists of interesting folks on Twitter without having to do a lot of work.  This is a service that is well worth checking out.
