One thing that's always fascinated be is the evolution of language, and I'd never thought of the change in the use of the word lol as anything along those lines. I always felt kinda embarrassed when I would use the word lol when I didn't actually laugh out loud, but now instead I'm going to think about how it's actually being used and what for. That goes for everything now when communicating in short quick bursts of text. When I find I'm using language in a different way than normal instead of feeling embarrassed I'm going to think about how I'm helping to create a language.
