I wish I had stayed out of this from the beginning, I see no merit in arguing about whether HN has some themes. I’ve been watching it daily for a long time as you can tell from the age of the account.
If you want to do something that would be both a good call as a mod and a favor to a longtime user, just whack this whole thread. I was trying to chime in with some knowledge but just wound up pissing everyone off.
One thing I can offer from years here is: never underestimate the silent readership (I'd say silent majority but...associations). The vast majority of readers don't comment and most don't vote either. It doesn't mean they aren't following and getting a lot out of what you wrote. Usually it's only the most-provoked segment of the long tail that is motivated to respond. That's fine, it's the cycle of life on the internet—but it doesn't represent the whole community.
Please comment more.
