I would say that Reddit is an intentionally designed dopamine machine with *many* areas of usefulness. Most of Reddit is pretty great. One example, /r/formula1 is the huge engaged community that every sport wishes it had. Live race threads are as close to watching the race with a bunch of friends in the room as it gets. Same goes for most interests: the biggest community about it is probably on Reddit, and most likely the majority of the content on its sub is pretty high quality. I do agree it can be a chore to find these communities. Especially when their name is only tangentially related to their thing (small example, the subreddit of the 90's show "Friends" is /r/howyoudoin). Reddit definitely needs to have some way to "tag" subreddits, and search on those tags. Finally, indeed the default Reddit experience is a sort of clickbait dopamine machine of /r/pics, /r/funny, /r/me_irl etc. One the one hand this sucks, on the other hand, it keeps the casual low effort lurker out of your high quality subreddits.
