Selection of Instant Messenger for Linux

After trying licq, gaim and kopete I decided to use sim – just another IM for KDE. It has pretty good user interface, supports UTF-8, allows to define encoding for each person in the contact list. It’s intergated to KDE (I like it and use only it). So, there is an only one problem. Yahoo! client cannot work via proxy. But this’s because Yahoo! doesn’t want to open its protocol and offer API.
SIM is also available for Windows and MAC. It supports all known IM protocols and in additional Livejournal connetion (I didn’t test yet).
Anyway, I’m happy and I’m ready to talk 🙂
