Uh, that's not how I read this at all. The linked document is not a policy document. It isn't defining micro-promotions either. It is a response to the general question "how can I help?", in the form of a practical list of example actions that someone could take if they wanted to do something to improve the situation. There is no implication that you have to do all of them. In fact, just the opposite -- it is presented as a Bingo card, directly suggesting that a given person is only likely to do some random subset of everything listed. It's linked from "micro-promotions" because it's relevant. That's all. If you have no clue what the term is about, and you go to the link, you can now say "oh, promotion as in encouragement or countering bias. Ok, at first I thought it was small meaningless title changes or badges or something." I enjoyed the article and mentally filed it into my "things to keep in mind" category. I'll probably think of it when I do my next code review. Not "oh, I have to say something nice! Uh... your indentation is absolutely perfect!" I'm not into meaningless positive comments; they devalue legitimate praise or gratitude. But I already face the choice of whether to do a basic "lgtm" vs something like "cool, this is a lot easier to follow now" or "thanks, that's been bothering me for some time." And this is a reminder of valid reasons to say something more. Even though most of the time I'll still be sticking with "lgtm".
