I remember years ago reddit was a lot more like HN. The comment section (even for the main subs) was much more intellectual and critical.
People appeared to actually read posted articles. It was a thing where people would read the comment section before the article because everyone knew headlines were generally clickbait, and you could rely on some internet stranger to have analyzed the article and demonstrate the headline wasn't all as it seemed.
But now it seems that no one reads the articles at all or care for any sort of discourse with people with different opinions. Comments are filled with just jabs and pitchforks. No different than comment sections on news sites. Yet Redditors still seem to have the arrogance that it had developed over the years that their communities are better than those sites. And well, they used to be, but now they're just as bad.
