Too long, didn't.... wha?

I'm starting to see tl;dr used more and more frequently, not as an declarative statement, but as a noun, as in "Here's the tl;dr of the story." This troubles me.

What does it say when ignoring something somebody else put a lot of thought into becomes so common that there is a cute slang name for it?

(Anyone who answers "tl;dr" is guilty of the cardinal sin of predictability.)
