How about an FPP mentoring/buddy system?
I've noticed that when talk about posting FPPs comes up, there's a not-insignificant number of people who say "I have ideas sometimes but I am uncomfortable posting them as an FPP because I don't know enough on the topic/I'm not sure how to frame an FPP/people will threadshit/etc." I've also noticed that there are regular deletions of FPPs that, were they run by a knowledgeable third party first, would never have been deleted because someone would be able to say, for instance, "no that's way too axe-grindy." And I can totally understand the self-consciousness that would keep MeFites from running their ideas by the mods (as they often suggest.)
So what about some sort of directory, whether on the Wiki, on the site itself, on profiles or wherever, of MeFites and their chosen mentoring topics. So, for example, if someone has an idea for a video gaming FPP and either doesn't know if it is worth fleshing out or maybe it is finished and the framing seems hinky, they can pull up the directory and see "oh, hey, griphus volunteered to look over videogame FPPs, I'll send this to him" and then I can look it over and give some feedback. We have experts of lots and lots of things here (including on how to make an FPP) and something like this would improve the overall quality of what is posted to the front page. There wouldn't be some sort of official seal-of-approval process, but just an easier way for users who want to make FPPs but don't necessarily pay attention to who posts about what and don't know where to turn (and, again, are reticent to ask the mods.)
