HPMOR is really cool, but I've also known several people who can't stand it. Too long/too Gary Stu/too strange for devoted fans of the original series. Luminosity is just as good, but suffers from some of the same issues. I think we need more short stories that have reasonable, non-utopian endings, things people can pick up and read in an hour. Though I say this knowing I likely won't be in a position to write any of these stories for a while...
