Note that I'm not saying ignoring it is the best approach. I just don't like seeing a bare "RTFA" when the issue raised was not specifically addressed in the article. (Even if it can be arguably inferred from the article, some pointers at the steps of inference are worthwhile - things are not equally obvious to everyone).

I felt that the aside about social gamification was important conceptually.

As technologists, sometimes we build something and then like to step aside and talk about it like it's inevitable. But how it was made and how it works factors in to how it is used. So it is our responsibility.
