Since this is no longer connected with Scratch, I propose that we get rid of the "on-topic" requirement for posts. Misc. is about just hanging out and discussing things and if a certain discussion topic strays from the original post's topic, I don't think that's necessarily a bad thing. And likely, it won't really disrupt flow of conversation because typically, any particular topic will slowly veer "off-topic". But just because it's off-topic, doesn't mean that it's not worthwhile. It's just how like in real life people typically don't talk about the same thing for hours and hours: instead, they let the conversation ebb and flow and one topic will usually lead to another.

I think it's okay if threads go somewhat or fairly off-topic, but I think there should still be focus on the topic of a thread and also no threads created without a central topic. But discussion beyond a topic (esp. if somehow related, even if only tangentially).
