At the moment on Windows I use
Trillian to sort my on-line social networks (Facebook, Linkedin, 2 Twitter accounts)
They do have a Linux beta but it only supports chat at the moment and not making status post which is what I require for work and personal.
I need something that can fit the bill and allow me to post updates to all the accounts or some of the accounts depending if its work related or personal updates.
Done a quick Google but nothing really stands out. if nothing can fit I was going to look at installing Wine and running the windows client of Trillian but before looking in to the ins and outs of this wanted to make sure I have not missed a trick.
Using Fedora 20.
