While I see your point, I think you're not giving Scratch enough credit. Admittedly, I don't know the culture around it today but back when I was a child the Scratch community was made up of kids who were there by choice, not because adults presented it to them. I certainly found it on my own, and had a swell time tinkering with it.

I'm not sure what you mean by this? I don't remember anything about winning besides the whole social media aspect of trying to get popular among all the cool projects that other people had by getting the largest number of likes and remixes.
