I just edited the question selection for my site and some text and manually pinged my mod team to alert them. I wondered if we would get notified of at or also if a trusted user made a substantial edit to the question at hand.
It would be nice if the moderators for a site got a notification any time the about page changes. This could be the result of someone editing it (us or a SE employee) as well as if the question we have chosen gets edited by a user.
I'm assuming the site isn't coded to cache the question when it is selected and a malicious edit (or simply a clueless edit) could render the selection of a particular question for the about page less than desirable.
As much as I like a less-noisy notification system, I feel it would be good to have more eyes on changes systematically rather than by chance. (especially since our users can't themselves flag the about page if they see something amiss there)
