FREE TWITTER CLONE WEBSITE - NEW OPEN 
SOURCE & MICRO BLOGGING SERVICE 
CALLED IDENTI.CA

"Connect your friends, groups or offices into a public or 
private network to share information - it's so easy...!"

Identi.ca is an open source social networking and micro-blogging service. Based on StatusNet, a micro-blogging software package built on the OpenMicroBlogging specification, Identi.ca allows users to send text updates (known as "notices") up to 140 characters long. While similar to Twitter in both concept and operation, Identi.ca provides many features not currently implemented by Twitter, including XMPP support, geolocation, personal tag clouds, and groups. In addition, Identi.ca allows free export and exchange of data based on the FOAF standard; therefore, notices can be fed into mobile apps, Twitter, Facebook and other social-media platforms or ported into private systems like Yammer.

Identi.ca supports the OpenID standard for single signon between Web sites. OpenID lets you log into many different Web sites without using a different password for each. If you have an account with Yahoo, AOL, Blogger, Wordpress.com, LiveJournal, Vox and others - you can log in to Identi.ca by entering your AOL-provided OpenID (read instructions here).
