Share Your OPML needs more users

Michael Arrington: "SYO (Share Your OPML) needs more users. My guess is a few thousand have already uploaded their reading lists, but it will take a lot more before the data is really reflective of what most people are reading. To do this, SYO needs to add more value than it currently does for users."

I think that in order for the service to become truly valuable, there do need to be many more users. I wonder if it would make sense to partner with some of the larger aggregators such as Bloglines or NewsGator to allow people to more easily opt-in to sharing their feeds? Not sure about the business implications, but it would grow the database rather quickly.
