Part of the problem is that the tour page has somewhat of a fixed template. We can't change the text "Don't ask about", for example. We can only change the bulleted list below it. So something that is a little bit nuanced, like homework, probably cannot be fully explained in this format.
I think we also probably shouldn't... overestimate the impact that the tour page has. I don't think that changing the wording will have a measurable impact on the questions asked.
With that said, I do agree that the wording can be improved (if only for the sake of internal consistency). And since it's an easy fix, I don't see why not to do it. My proposal would be:
Don't ask about:
- Your homework, unless you also describe your attempts to solve it (homework policy)
Please feel free to also propose alternative wordings, if you don't like mine. But if there are no significant complaints then I will make this edit in a few days' time.
