He just learned that keeping secrets is bad in general, and so he doesn’t by default, unless explicitly agrees to.

This is not true! My policy is simply that you should not assume that I will promise to keep your secrets after you tell me, if you didn't check with me first.

I can confirm; Oliver keeps many secrets from me, that he has agreed to others, and often keeps information secret based on implicit communication (i.e. nobody explicitly said that it was secret, but his confident read of the situation is that it was communicated with that assumption). I sometimes find this frustrating because I want to know things that Oliver knows :P 

And he sent the message in a way that somehow implied that I was already supposed to have signed up for that policy, as if it's the most normal thing in the world, and with no sense that this is a costly request to make (or that it was even worth making a request at all, and that it would be fine to prosecute someone for violating this even if it had never been clarified at all as an expectation from the other side).

Speaking generally, many parties get involved in zero-sum resource conflicts, and sometimes form political alliances to fight for their group to win zero-sum resource conflicts. For instance, if Alice and Bob are competing to get the same job, or Alice is trying to buy a car for a low price and Bob is trying to sell it to her for a high price, then if Charlie is Alice's ally, she might hope that Charlie all will take actions that help her get more/all of the resources in these conflicts.

Allies of this sort also expect that they can share information that is easy to use adversarially against them between each other, with the expectation it will be consistently used either neutrally or in their favor by the allies.

Now, figuring out who your allies are is not a simple process. There are no forms involved, there are no written agreements, it can be fluid, and picked up in political contexts by implicit signals. Sometimes you can misread it. You can think someone is allied, tell them something sensitive, then realize you tricked yourself and just gave sensitive information to someone. (The opposite error also occurs, where you don't realize someone is your ally and don't share info and don't pick up all the value on the table.)

My read here is that Mikhail told Habryka some sensitive information about some third party "Jackson", assuming that Habryka and Jackson were allied. Habryka, who was not allied with Jackson in this way, was simply given a scoop, and felt free to share/use that info in ways that would cause problems for Jackson. Mikhail said that Habryka should treat it as though they were allies, whereas Habryka felt that he didn't deserve it and that Mikhail was saying "If I thought you would only use information in Jackson's favor when telling you the info, then you are obligated to only use information in Jackson's favor when using the info." Habryka's response is "Uh, no, you just screwed up."

(Also, after finding out who "Jackson" is from private comms with Mikhail, I am pretty confused why Mikhail thought this, as I think Habryka has a pretty negative view of Jackson. Seems to me simply like a screw-up on Mikhail's part.)

Second one seems reasonable. 

Clarifying in the first case: If Bob signs up and DMs 20 users, and one reports spam, are you saying that we can only check his DM, or that at this time we can then check a few others (if we wish to)?

Not sure if you're intending to disagree, but I do sometimes have like a post-list or the quick-takes fail to load, with a red error message instead, and then if I refresh it goes away.

(I can't recall it happening very often, mostly I see it when I run a dev instance.)

I have a hard time imagining someone writing this without subtweeting. Feels like classic subtweeting to me, especially "I think this is pretty obvious". Like, it's a trivially true point, all the debate is in the applicability/relevance to the situation. I don't see any point in it except the classic subterfuge of lowering the status of something in a way that's hard for the thing to defend itself against.

My standard refrain is that open aggression is better than passive aggression. The latter makes it hard to trust things / intentions, and makes people more paranoid and think that people are semi-covertly coordinating to lower their status around them all the time. For instance, and to be clear this is not the current state, but it would not be good for the health of LW for people to regularly see people discussing "obvious" points in shortform and ranting about people not getting them, and later find out it was a criticism of them about a post that they didn't think would be subject to that criticism!

There is a strong force in web forums to slide toward news and inside-baseball; the primary goal here is to fight against that. It is a bad filter for new users if a lot of that they see on first visiting the LessWrong homepage is discussions of news, recent politics, and the epistemic standards of LessWrong. Many good users are not attracted by these, and for those not put off it's bad culture to set this as the default topic of discussion.

(Forgive me if I'm explaining what is already known, I'm posting in case people hadn't heard this explanation before; we talked about it a lot when designing the frontpage distinction in 2017/8.)

I think most of the people involved like working with the smartest and most competent people alive today, on the hardest problems, in order to build a new general intelligence for the first time since the dawn of humanity, in exchange for massive amounts of money, prestige, fame, and power. This is what I refer to by 'glory'.

I think of it as 'glory'.

Perhaps a react for "I wish this idea/sentence/comment was a post" would improve things.
