Moderators can choose an example question for the about page of their site. But we can't choose from all the questions, but only from a limited subset. This leads to the following situation on Skeptics, the full list of available questions is:
This isn't much of a choice, only a single question qualifies for the about page and that one is not really a good example for new users. A very good example for a Skeptics questions usually contains at least one link and a blockquote, and is often a bit longer.
I'd propose to change the criteria which restrict the available questions, but then I was unable to find those criteria in the first place and don't know which would have to be changed.
So what are the exact criteria for a question to be eligible for the about page?
