I'm worried that some of the humor that we see in certain common places, like poetry discussion or perhaps off topic, may prove off putting to new users.
I'd like to see people be able to joke, or discuss anything of any topic - but I feel that the big channels should be more tame and SFW to help welcome new people. I recently saw the introductions list, and there are A LOT of lurkers here. I want them to feel comfortable to chat with us if they so wish, how they wish.
People could still be silly, it just wouldn't be at the first place people might see when they visit the server.
