Joomla K2 is one of the top north CCK extension for Joomla, we can use it for making news site, blog, catalog site,... out of the box.

Lots of Joomla webmasters have been asking me to make modifications to K2 CCK to make it post to Twitter, Facebook, LinkedIn, Google Buzz, ... every K2 item posted.

It's now easy and out-of-box with a solution from foobla by using obSocialSubmit with K2 add-on. Your K2 items will be in Twitter, Facebook, Google Buzz, LinkedIn, Ping.fm, ... automatically.
