I have no idea how high their standards are

My impression of fic standards in Potter fandom in general are, well, that they are not high. :) Thus, you see, you are needed.

Please do friend, yes! Although I'm afraid I'm only on DW; I know this sort of cuts me out of the main action on LJ. I'm also fairly new to Potter fandom, so I don't have many HP folks myself. (And, honestly, I'm so used to small fandoms that Potter fandom intimidates me a bit, so I'd be entirely happy to form a nice, cozy little Potter cabal, and I suspect there are significant overlaps in your taste and mine.) :)
