qTwitter

qTwitter is an application interacting with microblogging services, such as Twitter, Identi.ca and others based on StatusNet application (former laconica). It aims to be as compact as possible still providing outstanding usability. Since it's a Qt-based application with no other dependencies, it works wherever Qt does, i.e. Windows, Mac OS X and vast variety of Linuxes and Unices supporting X11 (including Nokia's Maemo platform).
