What all HN readers know and need is a good balance of humourous as well as serious content. Humor is not easy. We should cut humor-aspirers some slack and never vote while angry.
While HN isn't perfect, I think overall it's extremely well moderated. Although I have to admit (and I have other accounts which are much older, so I'm not new here), it does seem to be slowly slipping in the wrong direction as it becomes more popular.
The reason I made another account after that is this account specifically seems to have its comments automatically moved down the list. It's easy to find examples where upvoted comments sit below grayed out comments, and oftentimes when I post a new comment it immediately starts at the bottom of the pile.
