Why are you not on Twitter

Over the last 2 weeks I have found myself asking that question more times than I can remember. When I first heard about microblogging (http://en.wikipedia.org/wiki/Micro-blogging)—or Twitter, the primary service that started the microblogging movement—over a year ago I thought it was a stupid fad and wouldn’t last. I mean what value can possibly be passed along in 140 characters or less. 2 weeks ago I was convinced to try Twitter (http://www.twitter.com/) and I am hooked.
