Was looking for a decent plugin or module for generating sharing buttons on a Joomla! site.

Finally ended up using SocButtons, which has the possibility of Google +1, Facebook Like, Tweet in Twitter and Share in LinkedIn buttons at the top or at the bottom of a Joomla! website's articles.

It also lets you to choose the categories on which you do not want the sharing to appear.

Available for all, Joomla! 1.5, 1.6 and 1.7.

Link to SocButtons on Joomla Extensions Directory.

Neat plugin and simple setup.
