There are no "mods" on HN. There is one singular admin, dang, who pretty incredibly manages both the tech and the community.
In terms of people who have the power to downvote comments or flag stories, these are just regular HN users. There is a karma threshold at which downvote and flag links appear, but there is otherwise nothing special about this ability.
Some folks may think I'm splitting hairs, but I think it's important to clarify, as I often see comments blaming the "mods" for e.g. a post that was downvoted or flagged, as if the mods are some shadowy cabal (which can be the case when referring to Reddit mods). If posts are downvoted are flagged, it's because the community at large didn't like what you had to say.
I didn't see the original comment and I may take this better since it isn't my code but I don't ser this comment as negative.
If gives clear criticism which I can easily brush off as the way I want my library to work, but that when I read it I can agree with.
One if my major gripes with many libraries doing asynchronous work is that they just blindly assume I will be using their blessed event loop when in reality I already have an event loop. Which means I now need to put their code in a new thread, regenerate events and pass that to my event loop, that tends to add complexity.
.. but likely more than either of us get paid to comment.
