One place this shows up is a frequently-expressed sentiment that the internet is a less magical, less weird, and more corporate place than it was 10-20 years ago. Part of this may be because SEO has diluted the voices of individual creators. But part of it is also because way more average, everyday, tech-unsavvy people are on the internet now.
Another example is the periodic highlighting of somewhat garish HTML-based websites. I like these too! My own personal website falls in this category! But as far as I know, the generic internet user likes the generic slick-graphics-and-whitespace style, and so go the websites that want to attract them.
More relevant to the topic at hand, many comments in this thread argue that targeted ads are unnecessary for a functional internet, since the internet of 20 years ago seemed to work just fine without targeted ads. But, again, it's less clear to me that general internet users -- that is, mostly people who never experienced the internet of 20 years ago -- have the same preference.
It's funny, because I'm to a large extent on HN's side on this one. But my enthusiasm is tempered by my sneaking suspicion that the other side is a lot bigger, and my side is actually powered by more elitism and nostalgia than I thought.
