Well, to be fair, it isn't an issue anymore since Harry hasn't been underage in canon now for a number of years and a lot of new fic tends to be mostly canon-compliant. Heh. But I do know what you mean. Like I said over there, I think for myself it helps that I'm not a visual person because I never really had much difficulty reading chan. Especially when you consider that Harry is almost always aged-up in fic. And within the Snarry relationship the usual difficulties people run across in student/teacher and cross-generational pairings (violation of trust/power differential), don't seem to be problematic with this pairing. At least not in the same way I would see Remus/Harry or Sirius/Harry.
