Thanks for making me feel old.

I built an app wirh ruby on rails 0.5.0 back in July 2004. It was what lead to working on Odeo. We made an app for sms blasts. Then I got the job building Odeo because I was one of only two people in the San Francisco bay area with rails experience. Later we used the sms stuff combined with blog posting and reading and the dispatch status updates system. And it became Twitter.
