Your blog post mainly consists of the statement:
"Get a clue, people. Hacker News is an awesome discussion forum because it serves a business purpose. Please stop acting like there is something bizarre or ethically questionable about the mods making sure that this free service actually serves the business that pays all the bills for it. Geez"
I don't agree with the the assertion that HN mainly "serves a business purpose", perhaps in its early days its main purpose was to funnel prospective people into YC (second step from pg's essays, I stumbled on HN this way back in the day).
While you consider the arguments as "inane", I think there is merit in people trying to understand the mechanisms on which HN is being moderated. The "Don't worry your pretty head, it's being done right" argument only drives up more suspicion, because this is exactly the way less than savory practices in government and elsewhere are hidden. I don't think this is the case with HN but trying to argue that the suspicions arise not (just) because people are just jerks or stupid.
