Re "please make it possible to block specific users" - this has been on the list for a long time but I have a feeling that it may go against the community in the long run. The more I get to know HN, the more I realize how important the non-siloed property is—i.e. everyone's in one big room together and can't self-select to get away from each other [1]. Of course, that makes HN a place where we all run up against things that are not only unpleasant, but actually shocking [2]. But I think that learning collectively to deal with that—learning to tolerate what that does to our nervous systems—is core work we have to do together, to keep this place vital.
Each internet community begins with different initial conditions, and if it goes on for long enough, those initial conditions get a chance to unfold into something unique. Trying to change the initial conditions after the fact feels to me like a bad idea. It's better to find ways to live with them, and maybe to steer their consequences, like sweepers in curling.
