I can't wait until authors start using lol, lmfao, j/k, ldo, chillax, f*cktard and many others just so they stay current and don't seem to be putting on airs by using some actual words that apparently no one knows the meaning of anymore.
That will be real literature written for real men by golly!
As for LF, I do find the category name to be rather vague and unhelpful to me personally but to each their own.
I do find it annoying when someone comes out with "so you mostly just read genre fiction then?" in a tone akin to having realised they have just stepped in something icky. I'm sure it's a massive generalisation but in the circles I mix in it does seem the only judgmental people when it comes to book likes and dislikes are the ones who like LF.
