Now You Can Follow Twitter Users Without an Account →
Twitter has introduced a new feature called “Fast Follow” that makes it easy to follow anyone via SMS, even if you don’t have a Twitter account (if you’re located in the U.S. at least).
To use it, all you need to do is text “follow [username]” to Twitter’s shortcode of 40404. From there, you’ll start receiving all of that user’s updates via text message.
