It has been a while since I wanted to RSS a Twitter feed. It used to be that every user’s Twitter page had an RSS feed with it, making subscribing easy. That changed at some point (early 2011 based on time stamps of people trying to figure the new situation out?). Mainly for self-reminder purposes, here is how to create an RSS feed off a Twitter page/feed:
(1) Learn the user id for a Twitter account by copying and pasting the Twitter account name into idfromuser.com.
(2) Replace XXX with the user id in this url: https://twitter.com/statuses/user_timeline/XXX.rss
Note that there were a couple times that Google Reader was not able to subscribe.
