A friend of mine asked me today if it was possible to subscribe to a person’s tweets via RSS. After a bit of poking around, I found the answer. Use this, replacing my Twitter name (scottgranneman) with the Twitter name of the user you wish to follow:

http://api.twitter.com/1/statuses/user_timeline.rss?screen_name=scottgranneman

Works in Google Reader & other fine RSS readers everywhere.
