I don't like the mob thing either but it's how large group dynamics on the internet work (by default). We try to mitigate it where we can but there's not a lot of knowledge about how to do that.
A lot of people who are stomping mad are mad because they think, for example, that you personally flagged #Thing and don't realize that's not how that works. A lot of that -- the best antidote is calm, cool education without getting cranky, etc.
In my experience and similar provisos.
It may be that there's a level-up here that we haven't achieved yet. But answering complaints and pushback is such a big part of what I do, and takes so much energy, that I'm scared to make more of the admin stuff public. I know it would explain things and have a settling effect for some; but others would misinterpret the information and get even more riled up by it. What the total effect of such a change would be is impossible to predict, but if it were 10x of the latter (the nightmare scenario), I'm not sure my heart could take it.
It works quite well. I'm much more true to myself and get into fewer combative situations. I bet it would reduce complaining to mods on HN as well. The site could still use points exactly the way it does behind the scenes, but users would be less concerned about their own status.
