I've been making a conscious effort to be less of a dick online recently. I find that it's very easy to rip apart words someone has written, but I've been trying to remember they represent someone else's thoughts, beliefs, ideas, things resulting from cat walking on keyboard, questions, problems or otherwise. And so rather than giving snarky or rude replies to dumb questions, ludicrous ideas or implausible beliefs I've been more careful about how I word things. And it's a little less fun, maybe, but I think it makes a positive difference.
