Most Unique Subscription Lists

Andrew Grumet: Most Unique Subscribers. Brilliant hack of the Share Your OPML SDK over at The basic concept, as invented by Chuck Welch in a comment on Andrew’s blog: add the number of users subscribed to each feed in your subscriber list and divide by the number of feeds in your list.

My number is 46.27 (based on the list published on the site; I need to upload a new list, since I now have 161 feeds in NetNewsWire (up 40 from when this started two weeks ago). If Dave’s new tool has done anything, it’s turned me into an RSS fiend.

One note: the more customizable feeds like the iTunes Music Store’s offerings become available, the higher everyone’s uniqueness number will rise.
