IRC Client of Choice?

[RichardGv]

Irssi. Fast, elegant, extensible, and does not crash when I restart X server. :D

1. My computer is severely short of memory (well, 1GB is just not enough if you compile something everyday), and irssi uses a (relatively) tiny bit of memory. Typically 7MB or less.
   
2. Irssi can be easily extended with Perl scripts.
   
3. Irssi has little library dependencies, and works when all other clients don't, like what Zack pointed out. Well, unfortunately irssi does not run on iPod or phones, but as a poor Chinese (instead of a rich American :D) I have neither of them.
   
4. I always have a paranoid will to do everything in the terminal or framebuffer. :)
   
5. Using irssi makes me look like a Linux expert, even though I'm only a beginner. :D
