StatusNet

StatusNet (formerly Laconi.ca) is software using the OStatus protocol (formerly OpenMicroBlogging). StatusNet is a free and open source (AGPL) microblogging platform. It helps people in a community, company or group to exchange messages over the Web. (These are typically short messages, up to 140 characters, but the settings can be changed when using your own install, or a Status.net cloud account.)

The flagship website powered by StatusNet is Identi.ca.
