I think it's a good thing. I mean, the dictionary's to tell you what things mean, not whether or not you should use them in your homework, or whether or not they're silly. There are probably plenty of other words you shouldn't use in your homework that are in the dictionary. Also, on encouraging "gradual illiteracy"—language changes, and it would be nice to understand, and so many people use those abbreviations anyways, so what difference does putting them in the dictionary make? It won't hurt anyone to put OMG and LOL in the dictionary, and it'll probably help some confused person who's just gotten a text message that has them in abundance.
To AF: Then Artemis would say, "I don't like LOL's," before scolding himself for using slang.

I'm trying to care, Artemis. But I thought it was all supposed to be over when the fat lady sings. Well, she's singing, but it doesn't appear to be over.—Holly Short
