I think the king of command line clients is TTYtter - I love it.

To my great sadness, TTYtter is currently unmaintained (I sent in a bug report and that's what the dude told me). So I expect it to stop working at some point. Until then, best desktop Twitter client for me by a mile.

I wish Twitter, Inc weren't the absolutely stinking worst maker of Twitter clients. :(
