Oddly this reminds me of a weird thing. (Not trying to attack you or others here btw, for reasons that I will make clear in the end). When I was active in student activism, I recalled how annoyed our leaders of the group were that a small but vocal (and inactive) part of the organisations membership didnt allow the leaders to be people.
When they (after already working crazy hours btw, these people were committed), spend some time in the evening to wind down and make some sort of joke(*), the inactive members alway would start to send angry emails. 'how dare you make an internal joke while students have less rights/the uni isnt eco friendly/etc". I though back on how that impulse from inside to org was indeed quite weird. Esp as the people complaining didnt seem to be that active members. (If they were they would know how much work was being done and the strain people were under and how the jokes were good for morale).
Something to take into account if you see lesswrong people react negatively to the hat post.
Of course none of this applies tonus as outsiders who do not take them that seriously at all. It is a weird thing to make a long post about indeed, esp with one of the hats being one of yuds it seems? Im wondering if this lesswrong thing is perhaps more of a personality cult that anything serious. A well at least nobody is using the org as a dating hunting ground, that would be bad.
*: basically they would spend their whole day prepping for meetings with the uni/other orgs, sending out emails trying to get the members to help out, doing research and summarizing that for the members etc etc, and at the end of the day they send one internal email about talk like a pirate day, and the next morning they get 21 replies to their work, 20 of those people being mad about the talk like a pirate email.
We have already all died and been uploaded, but it happend so seamlessly nobody noticed.
