You're looking back wistfully at a point where another user thought HN had fallen off precipitously.Yes, I think that's what made it a good example.
The other cycle I've noticed is these efforts at self-policing and reflection. I'm almost annoyed by them because I don't see HN as getting worse.
Yes, it's almost an inside joke. One of the "classic" HN stories is the meta story where we all lament the decaying state of HN. The "naval gazing" stories. You learn either to ignore them or vent (politely) After watching them for a while, I think they serve to help release a lot of frustration people have.
I would note that many of the folks early on who said HN was fine are now also saying there are problems.
To me, HN's core problem was the problem you always have when speaking to more than five people: trying to anticipate reactions. You end up trying to cover every possible response, and it kills the tone. One of the reasons my comments run on so long is that I have to cover every obvious way they could be misunderstood. You're stuck either not replying to anybody, writing long comments, or getting in endless debates. All of that is distasteful to me.
One of the hard lessons I had to learn blogging was not to tease people. I used to put pictures of girls in bikinis up or joke around about making money tricking people online -- to me I was just playing. I live by my reputation: being an internet porn mogul is not on my list of future plans. But there were a heckuva lot of folks who didn't understand my posts, who thought that made me some kind of evil person. It was really sad to have to give up the playful part of my personality simply to get along with people because of the many ways things can be misunderstood. I hate that.
But the real problem is that everybody's personality will piss somebody off somewhere. I know I probably rub thousands of people the wrong way just because I'm the way I am. Others do the same. So then I end up commenting something like "Looks like it is raining outside" and I get 3 or 4 downvotes. Sure, the upvotes outweigh them, but it's just silly nonsense. Vengeance voting.
Hey now I've rambled too, so we're even :)
