I don't laugh out loud very often when speaking to people online, and I've always hated the feelings of dishonesty I've gotten if I typed "LOL" when I wasn't really laughing out loud. So I never type it, except when I'm being overly silly and speaking in LOLspeak (usually to show that I'm being facetious).
But on the somewhat rare occasion when something truly is funny enough to make me LOL, I still don't want to type "LOL" because then it wouldn't convey how funny I truly thought it was, since it seems almost everyone types LOL for everything that's even slightly amusing.
So I guess I don't type LOL either way, due to its frequent misuse and abuse.
