The thing I have learned, especially in the Internet age, probably the easiest thing in the world is to declare that something is not funny. I mean it's not actually humor to say something is not funny, but it is viewed by a lot of people - and by that I mean mainly snarky young Internet men - as a kind of humor in and of itself is putting down other people's efforts at humor. And I don't care that much anymore about that because I know how easy that is to do.
I like to think of what happens to characters in good novels and stories as knots--things keep knotting up. And by the end of the story--readers see an unknotting of sorts. Not what you expect, not the easy answers you get on TV, not wash and wear philosophies, but a reproduction of believable, emotional experiences.
