Yeah. We are dipping our toes gingerly into the dangers of user feedback. Even on Scratch, it seems like each new user has to be taught how to behave (because their prior experience is, you know, YouTube and Twitter), and we don't have the staffing that Scratch does.
I'm pleased that we haven't had any major issues on the forum so far, knock on wood. We'll certainly get to adding comments to project pages.
I'm personally a little scared of view counts (let alone likes, which I hope we never have), because I don't want the experience to be about popularity. There's an amazing Scratch project that's a Scheme interpreter, using a list as a stack, but dating back to the days of no custom blocks at all, so it's just huge long scripts. It's not flashy and visual, and probably a dozen people have looked at it altogether, but if I had to choose a best-ever Scratch project, it'd be that one. (The author has no other posted projects and doesn't respond to messages, so I have no idea who it is!)
P.S. Now it'll go up to two dozen viewers... :~)
