My Reddit experience these days seems to be nothing more than using RES to scroll through images. I miss the good old days of in-depth discussions that were across the site and not just pushed into subreddits.
Ironically, content discovery.
Reddit's biggest problem is that the big subreddits are incredibly homogenous, and the small ones incredibly slow. If you want to read good, in-depth analysis of world affairs, then you'd better agree with the popular sentiment on /r/worldnews or /r/truereddit. If you don't, you're SOL.
Often, the good content you find is in the comments. However, this necessitates digging through thousands of comments that are generally low-content. This causes pain.
Want to solve a problem redditors have? Find a way to separate the wheat from the chaff.
There's definitely middle ground though. /r/DepthHub is pretty good at aggregating solid comments. And there's good debate on subs like /r/ChangeMyView and /r/NeutralPolitics. Admittedly, these subs don't refresh as fast as /r/worldnews, but there's usually new content every day.
What you really need is reddit for adults, a site with an entirely different culture that leaves the memes and unfunny jokes behind in favor of encouraging actual conversation on any given topic.
It isn't just the under18's that post memes you know.
Politics isn't a good
The best content on reddit that I find comes from niche communities. There are some really subject-specific knowledgeable people on there. You see those posts come through /r/bestof, which is just submissions to those gem comments that people find. It's worth subscribing to, but even that is a lot of noise to signal.
The only main/large subreddits I'm subscribed to anymore are /r/programming and /r/todayilearned. The other 50ish are for specific interests and hobbies.
Side rant: I swear that /r/technology went from a mature community of technically literate and rational people to a bunch of politically-charged kids obsessed with long-range scientific discoveries and product feature announcements in about a year. It was painful watching that happen. The patent war saga of yesteryear was the last straw that betrayed the community for the juvenile crowd it had become.
