On LOL

Of course "lol" doesn't mean I'm literally laughing out loud. It means I found whatever you just said somewhat amusing and I might have laughed out loud or at least grinned widely if we were talking face-to-face, but since I'm sitting in front of a computer screen it wasn't amusing enough to make me forget that I might look insane if I were to suddenly break out in laughter for no discernible reason.
