"Ubuntu usually ships with Gwibber, a micro-blogging client
preinstalled. It has all the features you need to manage Twitter,
Facebook and Identi.ca all in the same place. If you're just plain
tired with using Gwibber you might want to look at some other
alternatives that provide all the necessary features and more. The
Ubuntu Software Center has a few apps but they have a lot of
shortcomings, which made me move into these two which do not
feature in the software center."
