I’m sure you’ve heard of this project by now but for those who haven’t, OPML (Outline Processor Markup Language) is basically just your feed subscription list and “Share your OPML” is a site that gathers a community of subscription lists, in OPML format, and aggregate them in interesting ways.
The idea is similar to Technorati Favorites only more popular with readers considering the top blog in TF only has 472 people while SyO has 1,086. Still, not a lot for both though.
Share your OPML has some interesting features though, like the “Most Prolific Subscribers” (the top guy has 8,104 feed subscriptions) and “Who Subscribe to” which shows you who are the people who subscribed to a particular blog.
