OP you're getting a lot of criticism in this thread, and 100% going through it will be the best thing you have ever done. People are doing God's work here and you are to be applauded as well for wanting this honesty in the first place. Good luck.
I agree the author should be applauded. That said, trying to please everybody on HN is impossible.
It would be more useful if these comments explained why they think things are important, so the OP can assess the importance of feedback within the context of their own site. Too many of the comments assume all websites should be built in the same way, and criticise anything that isn’t.
