I microblog on Twitter, but have wondered about alternatives. Not only is there an open source alternative in Identi.ca, but it’s also architected in a decentralized way.
Identi.ca is an open microblogging service. Users can post short messages about themselves to Identi.ca, which are then broadcast to friends in their social network using instant messages (IM), RSS feeds, and the Web. The product’s developer, Evan Prodromou, joins Phil and Scott to discuss the project, including its open source license.
Identi.ca is similar to existing microblogging sites such as Twitter, Jaiku, or Pownce. Unlike those services, Identi.ca’s underlying software is available under an Open Source license. Identi.ca is also the first service to support OpenMicroBlogging, a standard for exchanging short messages between microblogging sites. Identi.ca also makes public user data available under a Creative Commons license in standard formats.
