A simple interface to a jQuery plug-in, originally written by heisde.de and thereafter re-written by the author.
The plugins offers the possibility of showing in posts (and optionally pages) buttons for sharing content to Facebook, Google Plus, Twitter, and Identi.ca. These buttons are dummy-button by default, and only after explicit action by the visitor they are activated and become the real buttons. This allows to give control to the single visitor if he wants to send 
sensible personal information to third-parties sites, and thus providing a nice compromise between privacy and social sharing.

different account on the same <a href="http://status.net" rel="nofollow ugc">Status.net</a> server.
The links to your blog can be shortened by one of seven different link shortener services like TinyURL.com.
