Searching Reddit helps but the quality of comments has gotten lower since 2015 or so. It seems to coincide with the wave of subreddit bans and the nakedly politically-driven moderation on subreddits. And with the reflexive attitude—against anything countering the Reddit consensus—that developed during the Trump years. High quality posters seem to have withdrawn from the site (at least in how much they comment) and what's left is mostly ignorant teenagers and bitter millennials with shitty jobs. In turn, that crowd is much less likely to upvote high-quality thoughtful content, so the cycle continues. The decline in quality has trickled even into the less popular subs. Don't get me wrong, the site has always had problems, but the more recent decline in thoughtfulness is dramatic.

The worst part is that despite Reddit getting so much worse, there is no other place that's grown to fill the void. This place is great, and I do search HN when it makes sense, but it's small and narrow in scope. Reddit basically crowds out any competing websites by sucking up all the low-level chatter required to sustain a community, but has also pushed away high-quality posters, who now have no place to go. Very tragic but maybe a good case study in shitty network effects.
