How many questions have you seen from beginners posting a very near complete solution with a minor typo, or posted complete solutions asking for how to complete the question better, where they’ve forgotten to mark their code as a spoiler?
Probably a lot, judging by how many times the regulars comment on it.
Perhaps it would be better to make the triple backticks have code as a spoiler.
I don’t think it takes away from the user experience to have to click - and by doing so they’re essentially saying “I don’t mind this being spoiled” anyway.
Thoughts?
