It seems rather unfair that you got upmodded so much, and curi's post 2 layers above got downmodded below 0. curi states a personal opinion, which is valid as one.
You say curi missed the most interesting aspect -- from your POV (and obviously shared by others). I disagree with you about what is the most interesting aspect, but I don't think your point is uninteresting, but neither would I think you missed the "most interesting aspect." I think the "most interesting" is merely the useful idea that "developing self-regulation is beneficial and important."
While there is really nothing wrong about the state of your, and curi's scores, and how much people agree with either of you, this points system makes it look like, at a glance, that something was wrong about curi's post, and yours was, relatively, +18 correct. This is a negative side effect of this point system, which I don't think most people keep in mind when voting.
