After two concerted-but-aborted attempts to wean myself off of Trillian in the last year or so, I finally think I’ve done it. I’m a Pidgin user now. Pidgin doesn’t support audio and video like Trillian does, but I find that I use Skype almost exclusively for online audio and video conversations these days, so those features weren’t key. Otherwise, the apps are damn similar – including the once or twice per day crashes – but c’est la vie.
The Skype IM integration and Facebook IM integration are just great on Pidgin – I’m way impressed. Lots of other neat plugins too!
