We've had this exact discussion a few times now, and the #C01932BJGE8 channel was created as a catch-all for this sort of content. It's for stuff that's not quite "on-topic" for the future of computing, but not quite off-topic either. The name "Present Company" is a play on words:
• If you want to talk about matters of present-day computing, this is the channel
• If you want to enjoy the company of others via lighthearted or playful digressions, this is the channel
We're using this name instead of "Random" or "Off-topic" because we don't want to encourage only that sort of stuff there. It's more open than that.
No, I'm not going to create a new channel just for memes and jokes at this time. Please post all memes and jokes in #C01932BJGE8. I don't for a second believe that the channel will devolve into frustrating noise and pabulum — on balance, this community has good taste. If the discussion there becomes too banal, I'll make adjustments. Not gonna do that defensively, though, because I'd rather let a thousand flowers bloom, you know?
