It's already happening. I've known about Exercism for a while and used it to teach myself Go. It was very effective and the feedback was immensely helpful, especially at first.

But when I went through the Ruby track (a language I'm already quite proficient at), I got almost no feedback, helpful or otherwise. Some of my entries would get one or two "thumbs up"s, but no comments, and most got no responses at all. Now that I've got a pretty good grasp on Go, my last couple of exercises there have started to follow the same trend.
