My first post to Twitter was on 6 October, 2007.
Goodness knows what I was doing with Ruby and Excel. I think it was something to do with trying to automatically process grades submitted by our African partners in the education project I was working on.
My first post to identi.ca was on 4 July, 2008, soon after it was publicly announced.
#laconica being the IRC channel for the software running identi.ca, since renamed to status.net.
I used Twitter for less than a year, and jumped ship because of ideology and downtime. After joining identi.ca and until recently I only used Twitter to support people doing Habari-related stuff. But recently there's been a critical mass of other interesting non-tech people who are on Twitter, so I've been posting more there, both directly when in conversation and indirectly through identi.ca.
The ideological reasons still exist, and I'd love to see both Twitter become more open and more federated microblogging, but at heart I'm a pragmatist. I think that means andyc would call me a sell out.
