Dave Winer has started a new site called Share Your OPML! On the site, Dave is attempting to create a community of feed subscription lists and aggregate the resulting data in various ways. He already has a Top 100 Feeds page up. Also, for each feed listed, you can see who is subscribed. A lot of people have already contributed their feeds. It’s rather interesting to see what some people read on a daily basis. If you use an RSS aggregator that exports OMPL, be sure to sign up and add your list.
