I have a casual and uncaring writing style in many places, but HN is not one of them. This is a place where I enjoy writing properly and reading properly-written comments, mostly because it forces commenters to put some thought into what they write.
When you're here, you know that the majority of comments will have something insightful to add to the discussion and you do not feel like you're wasting your time reading them.
Don't hate on this mindset. It's not appropriate everywhere, but it's not just a hippie concept, it has merits here.
