This is something that could have been equally effective as a brief email to pg. As the current top-ranked post here, it's kind of ... masturbatory.
This is the very definition of a meta post (and from a personal perspective I dislike the fawning tone too)
However, the impact of appreciating something and having communal pooling of appreciation affirms the intent. I want HN to remain what it is and I did not want to be "just another email" in PG's inbox; I suppose by submitting this in the first place I contributed to "what HN is not" but I do still feel that my submission was appropriate in the sense that my intent was an intelligent choice and not a "masturbatory" choice.
While I also like the same HN features you like, I didn't upvote your post because it just felt too obsequious.
This is an incredibly convoluted explanation of what can simply be called grandstanding. I appreciate your intent, but please - we all want HN to remain what it is. If your intent was to thank pg, email him. If your intent was to communicate your want for HN to stay the same - do so when there is some threat to what we hold valuable. Otherwise: post intelligent replies, downvote trolls and submit the occasional illuminating article. Threads like this (and others like it) do no good for any of your stated aims.
It can be curbed with a culture of self moderation, it can be curbed with enforced rules and other barriers, a good early example of this is Something Awful's combination of introducing a registration fee along with a reputation for banning users who posted crap. It's survived through the years and I'd venture this was a factor.
But the point is if your site becomes highly popular there will always be the risk of drowning under a low signal:noise ratio. Hence the sensitivity to posts like this here because <asskissing>the HN crowd as a whole has a lot of experience with this phenomenom</asskissing>.
Disagree - I think this thread will be far more well-read than the site guidelines by new members and will show them why we love this place and why we want to preserve it.
Nobody wants a post like on the frong page every week, but once per six months or a year is probably good for the community.
