Did so far :-
Tried Birdie (installed using using deb file, current status - starts but not working, unable to uninstall as well.)
Turprial (installed, started well, but not accepting PIN - tried numerous times)
Corebird - Heard that it is not stable yet, couldn't find a trustworthy PPA or deb file. So skipped till I am sure of it.
PS : Using Friends, but looking for a client with support for multiple accounts and better interface. Something like TweetDeck.
