Actually, we don't do too bad. Top topics come out as Entertainment, Music, and drummer. The Polarity on the drummer comes out negative, which is wrong but not surprising.

Reminds me of a gig my sister played when she was still in high school. Guy came up to her afterwards and said "girl, you play really *bad*" -- and she was all upset until somebody eventually explained the idiom to her.

I wonder how feasible it would be to handle genre-specific jargon like that -- say, treating "bad" as positive in discussions of music. Do people ever actually say "bad" in music reviews? Not much, I suspect; critics tend to find fancier ways of panning people ("full-time consideration of another endeavor, might be in order").

Which reminds me of a great book: "The Lexicon of Musical Invective". A huge collection of really scathing reviews....

Hi guys! Yes! interesting indeed.

Consider a really green lawn; a ceiling so moist that it's turning green; so called Green programming; or a really nice and moist chocolate cake compared to the embarrassment of moist hands...

Well, genre ID would be a good first step, and fairly tractable. Though here we want a mixture of genre (review, tutorial, discussion group, technical analysis,...) and domain (music, sports, cooking,...).

As long as your dictionary has information associated with specific word-senses or registers, and you have some information about the domain and register in  use, the word-senses can be picked out, probably pretty reliably.
