It's true that IRC is not free of tension and caustic groups. That said, like reddit, you can find very nice places to chat. #electronics #emacs both are very light on issues and very openminded (maybe too open minded some would say).
I talk a lot in #emacs and I do treat it like a coffee klatch, but when people come with questions, I try to interrupt myself and at least address their questions.
I like #emacs. It's like a gathering of friends who happen to use Emacs.
hi, i'm python476 (i know, awkward), so you know I share your sentiment about emacs. And #electronics is similar. Just a bunch of dudes who like that topic, but it's rarely on topic, and they're one of the most friendly bunch I've seen.
