Just to clarify, you don't need a Twitter account to follow someone and get their tweets by SMS. If you go to twitter.com/touchfans, you will see "Text follow touchfans to 40404 in the United States". No signup, no settings to change. Just text that number (may be different for other countries).

Oh, thanks! I wasn't aware of that. I was just adapting the post from last year, and didn't know that feature was added. I'll update the blog.
