Today, I stopped Twittering.
Yesterday, I became aware, as many did, of a service called identi.ca -- the first thing I thought was "Wow, that's the end of Twitter for me then"
The sad thing? I started hacking around on some ideas for my own Twitter clone last week, but I lack the commitment to really go through with it, which is great, because identi.ca is free software -- and not just any free software, but AGPL to boot.
I'm identi.ca/mattl of course, and some people have already found and followed me.
Earlier, I made this -- 'introducing identica' -- a guide to understanding what identi.ca is, for people who maybe haven't heard of it, or services like it.
It's really really fun.
