It was only a matter of time... great idea!
Ross Mayfield's Weblog: Identi.ca Launches, an Open Source Twitter
Evan Prodromou, one of the better citizens of the wiki community and founder of WikiTravel, launched Identi.ca today. Its a Twitter clone that is also distributed as Open Source licensed software. I've been playing with it in semi-private beta. Its made Dave Winer's day and Jevon is Canadian. Marshall Kirkpatrick has a longer writeup and sees promise in federation:
Identi.ca: May A Million Twitters Bloom
Identi.ca is a new microblogging service that launched today - but it's not just another also-ran. The service is an Open Source, CreativeCommons framework for a distributed network of federated microblogging services.
If you've become interested in the paradigm changing model of communication popularized by Twitter but have been frustrated by Twitter's frequent down time or other shortcomings - then Identi.ca could be for you.
Built by Evan Prodromou, creator of the wonderful site WikiTravel, Identi.ca offers a number of features that Twitter users will find of interest. We learned about the launch on the CreativeCommons blog; Identi.ca supports CC licenses for all the content that flows through it.
Note that initial interest is already challenging the first implementation of this service, they are working on improving performance but it will work best once there are multiple interoperable installs!
