I know I'm usually against topics, and I know revising the Topic List is on Tech's very (x1,000) long list of things to do, but is this a runner?
Everyone posts everything in Chat now (and in aibu, but that's another story [shudder]). And lots of op's seem to get very cross when people "chat" on their chat threads.
So how about a sub-topic in chat for people who want to talk seriously about things, don't want jokes and banter and what other people think of as chat, but want to stay on a single topic for the whole thread.
I think I some people default to _Chat because the topics are so complicated that unless it's a very obviously Becoming Parents: Pregnancy or Education: Primary Education (etc) thread one simply can't decide or even find where to put it.
But you mean a "Talk About Anything, But Stay The Fuck On Topic" place?
The trouble is that those of us who are here a lot, or have been here a long time, or both, tend to think of _Chat as chat - a place to chat.
Whereas newer posters think of it as a topic in which to ask questions and look for advice. So can't understand how people can descend on a thread, discuss the topic and move on (like a conversation in a pub).
They think that chatting is intentionally derailing, where it very rarely is.
Trills, the idea would be that all the chatters could hide the thread stay away if it's clearly labelled "serious".
I can see one potential problem though. I think few people would use it so it would be tumbleweedy. And then when the "banterers" suggest a thread is moved there, it would instantly die and the op would accuse the "banterers" of deliberately sending it off into the dark midsts of unnoticeableness.
