As the title says: I've noticed over the past month or so that a lot of new users tend to accept questions after only a couple of hours.
I know that it isn't mandatory for users to wait 24h to accept answers (like it is with accepting self-answers, I think it's 48h for those), and I have accepted answers myself before 24h is up (although I tend to wait the 24h these days), but generally everyone here considers it to be best practice.
Given that, I just checked the tour and found that it doesn't say anything about that, it simply says:
The person who asked can mark one answer as "accepted".
Would it be a good idea to update the tour to suggest that it's best to wait 24h? Note that I do not think it should become mandatory, just that it might be a good idea for this best practice to become more visible.
NB: This was written with the assumption that everyone was on board with the 24h thing. See accepted answer and my comment below it.
