Craig Hockenberry on the early days of Twitter when he was building the first Twitter client and users were still trying to figure out what the site was all about. It was so exciting to live through those early days.

Hashtags, @replies, and the first Twitter client — so much of what makes Twitter great was invented by the users in 2007. I still miss the days when you could use “track” to follow what others were saying about the iPhone and the site was still small enough that you could reasonably read all of it.
