The Origin of the @reply on Twitter

Yesterday, a post on Noteandpoint.com explored the history of the Twitter @reply. A followup [post today on ManicalrageCheck.com](http://log.maniacalrage.net/post/ 26935842947/the-real-history-of-the-reply-on-twitter) provides a little more clarity but still cannot nail down all of the details. Ultimately, this type of research would be much easier if Twitter allowed its user to access their entire tweet history.
