yarrr, ye scurvy boy-king, halt ye whinin'

Some classic books are now shelved in YA that were once in general fiction or general sci-fi/fantasy. You hear this often said of Ender's Game, or The Catcher in the Rye. There are those out there who cry foul to see these books shelved in YA. To which I say: whatever those authors may have intended, those books are YA all the way. Which is not to say adults shouldn't read them too, but only to say: they should be put where teens can find them, because teens will like them, and we should do everything we can to put books in their hands.

...Teens are an audience any writer would be lucky to get. Kids too. Kids and teens aren't going to pretend to like your books because the lit-snob aristoi tell them they should. You have to earn them. And if you do, you will have earned readers who will write you wonderful emails, read your book ten times and tell their friends to read them too, create art about your books, dress up as your characters for Halloween, sneak under the covers with a flashlight to stay up late reading. You will have earned readers who will be transformed, and who will tell you so. If you don't want them, you really really don't deserve them.
