Share OPML - 8000 feeds?

As many people have already commented, Dave Winer has re-created his OPML-sharing tool.  You can upload your OPML file for people to see who (and what) you subscribe to.  I can't imagine the general population playing with this.

About a dozen people subscribe to my various feeds, and I know about half of them by name.  Of those, I've met one.  Hi Doug!  FeedBurner says I have about 700 subscribers.

Of the "subscriptions like mine," I notice a gentleman who has 8000 feeds in his OPML.  And there are a bunch that have over 1000 feeds.  I'm guessing the participants are on the upper end of users.  I've got a mere 352 feeds.
