Almost every time I see someone use the heading syntax in chat, they were just saying a hashtag for a joke (e.g. #firstworldproblems, or #gonewrong).

Then it becomes a heading, and people are usually surprised or disconcerted or frustrated.

Could we disable the heading syntax for single line messages?

That and I'm philosophically against systems which don't behave predictably. Do we change the markdown guide with a bunch of (unless the message is on one line) type stuff?

Yes. ^

If there's a set of markdown which predictably doesn't work unless you have more than one line, that's good.

Mostly I just see things like list markup and headings being a regular pain in the butt for people to deal with, even those who've quite thoroughly learned the syntax. I can't start a message by stating a number then a full stop, or else it turns into a list with a "1" at the start.

That yes is "yes we'd change the markdown guide to say which things don't work if the message is on one line".

I would love this. The number of people who just want to use # for a joke and end up with massive text is pretty high.

This is on the testing server, but not as this was requested. Instead of a single line, which is vague and hard to determine, it is based off of if your post contains line breaks (i.e enter/shift+enter). With none of those, your post is considered "inline" and cannot generate things like lists, quotes, or headings.
