For me the difference between Chorley and Peter is that Chorley does feel fannish, whereas Peter feels more like someone who enjoys nerd-adjacent pop culture. (Lesley, on the third hand, engages only grudgingly with even mainstream nerdery.) But I do enjoy the critique of classic fantasy via Chorley as much as I wince because I, too, have a much-loved copy of the Dark is Rising series on my bookshelf.
