Might consider changing your acronym / label use, for sake of framing the discussion, as "GCAer" has pretty routinely been used to describe those of us lucky enough to participate here. When I read your title, I assumed you meant fan = casual, GCAer = serious student. Yes, the opening post clarified your point, but these things have a way of going sideways quickly. FWIW, I don't disagree with your general assessment (on % of fans vs access seekers).
