I was just as much a jerk as they were. But I got the last laugh.
But sometimes, particularly online, we can think small is useless. If you don't have ten million followers you're not worth much. If your post or comment didn't get noticed it wasn't useful. Bollocks. Small is good. I'll be happy if I go out of the world having done more good than I did bad. That's a small contribution but it's mine.
