When viewing someone's profile, you can see what I presume is their chronological user id. @jack, for example, is #12; @ev is #20. @paulg's recently created account is ~183M, and a brand new account came in at 185M.

Wonder if it's a bug or intentional that they're now releasing this info. I might not be update the app...

This info has always been available: the RSS feed attached to everyone's profile page is by ID.

For example, mine is feed://twitter.com/statuses/user_timeline/13192.rss
