I, too, find that I like fanon Hermione and my personal Hermione a lot more than I like the actual character. Then again, I think JKR's real strength is in the world creation and background, not the actual storytelling, so that's probably why. The IDEA of Hermione is so much more interesting than Hermione actually turns out to be.
I first encountered JKR's series about 10 years ago, and I have moved from really liking the books and not being interested in fanfic for them, to really liking the fanfic for the world and not much liking or being interested in the books.
I've been reading so much Harry Potter that I thought it should have its own page instead of just being on the Non-Whedonverse page, though it seems strange, giving it its own page since only the Whedon fandoms had that, and HP is so not on par with Whedonverse for me, on so many levels.
I have bizarre 'ship interests, but for the most part it's the potential of assorted characters rather than pairing dynamics that drives my fic interest (in contrast to most fandoms where I'm very interested in seeing just about everybody paired up).
So I decided that I would modify the grid format I used for BtVS/Angel and Firefly (stolen from Doyle) and just categorize the stories by which characters were major players in the stories, trying not to give away surprises.
Because characters are known by various names, the categorization and alphabetization is, well, creative.
If you would rather just browse through the fics I've found worth reading in this fandom, go to the list format here.
