I love that your son rewards strangers for creative effort. That wouldn't have occurred to me either, but I blame years creative criticism and a little internet pessimism for that.

While it is easier than ever to display creativity, I maintain that creativity itself is still hard as hell. Every story I write, every drawing I make is a pint of my blood and I can't imagine that ever changing. But mass consumption trivializes that effort. People can blow through something that took you six months to create in a few hours and then leave a comment like 'moar plz?', as if you could just whip up a sequel while on the toilet or something. I kudo and comment on stuff that really moves me, but I leave my digital 'hit' as a recognition of effort. And I never, ever troll. If I don't like something I just move on. Maybe if more people were like your son, we'd all feel the freedom to stretch and put ourselves out there...
