Diamond moderators can edit the new about pages. In the second section from the top--entitled "Ask questions, get answers, no distractions"--that takes us to an opportunity to select one of a page full of questions from the site as the example question used on the about page.
The selections currently available on physics are a little ideosyncratic. Is there some rhyme or reason to these?
I suppose that we want a good example question to
- be accessible to the intended audience (perhaps even to the newest and most naive person in that audience)
- be judged at least decent by the community (positive score)
- have more than one answer which are also judged acceptable (again positive score)
What else? How does a question end up on the list?
