Urrgh. We don't have a general channel for exactly that reason. We have a channel for general chit-chat that is nothing to do with work but that's as close as it gets. Anything else work related goes into subject/team/project specific channels. We even have a shoutouts channel specifically for bigging up someone who has done a good job at something.
general channels are cancer in any communication system as far as I've experienced.
