In this video, I discuss the newest Twitter clone, Identi.ca. Here s a quote from Bwana.org regarding it: Today, I joined Identi.ca. Is it YATC (Yet another Twitter clone)? Sure seems like it on the surface. Identi.ca offers a timeline view identical to Twitter, limits your updates to 140 characters, and it offers Jabber/Gtalk posts and updates. If that aint a Twitter clone, I dont know what is. [...] The software that runs Identi.ca, called Laconi.ca, allows users to run their own federated instance of the software. This has made advocates of a federated Twitter, like Dave Winer, very excited about the possibilities. I have went on record to say that a federated architecture is not also guaranteed to produce a successful Twitter, as there have been many stable non-federated messaging systems. They all had a sound design. Im not saying it wont work, Im stating that its not a silver bullet. Either way, its happening now that Identi.ca has entered the space. With juggernauts such as Winer excited about it, it can only be a good thing for developer momentum. If you re interested in Identi.ca, sign up today at http://identi.ca. Enjoy!
