Pidgin, the universal chat client
Rated • 94 reviews • instant messaging, im, pidgin • pidgin.im
Undeniably the best, most flexible, simplest text-only instant messaging program on the planet. I have twelve accounts defined in my Pidgin Portable installation and use it constantly throughout the day. In addition to the mainstream IM networks, easily installed plug-ins exist for Facebook Chat, Xfire, and more.
The only thing missing is voice and webcam support, which of course, hardcore IM'ers frown upon. :-)
ps. Regarding Mariavis' concern about IM BOTs (below), check out the Bot Sentry plugin.
