I don't, because I'm still using it! Me and a few internet friends have a cozy little community, and usually hang out there daily. IRC isn't really dead at all as far as I'm concerned, just not as popular anymore. It's the same as with people who complain that there's no good music anymore, it's there, they just haven't found it.

Anyways, check us out if you want, more people is always a plus: https://irc.orderofthetilde.net/
