Horrible idea that's somehow too good not to try pull off. Also, probably already considered years ago. But here goes anyway ;-)
One of this site's biggest dings against leaving beta is that we currently have an average of 1.5 questions a day, instead of a healthy 10 questions.
Working against this, it seems that a significant proportion of naturally incoming questions have to be closed as "too broad" or "too shopping list" — so much of setting up and operating a ham shack seems better suited for forums than the stricter SE policies, e.g. "I have [QTH situation] and [equipment budget] and [personal interests], please share your opinions!"
What if we filled this site in with every question on the FCC exam?
