Laconica (pronounced "luh-KAWN-ih-kuh") is a Free and Open Source microblogging platform. It helps people in a community, company or group to exchange short (140 character) messages over the Web. Users can choose which people to "follow" and receive only their friends' or colleagues' status messages. It provides a similar service to sites like Twitter, Jaiku and Plurk.
With a little work, status messages can be sent to mobile phones, instant messenger programs (GTalk/Jabber), and specially-designed desktop clients that support the Twitter API.
Laconica supports an open standard called OpenMicroBlogging <http://openmicroblogging.org/> that lets users on different Web sites or in different companies subscribe to each others' notices. It enables a distributed social network spread all across the Web.
Laconica was originally developed for the Open Software Service, Identi.ca <http://identi.ca/>. It is shared with you in hope that you too make an Open Software Service available to your users. To learn more, please see the Open Software Service Definition 1.1.
