Not the person you replied to but personally I’d like to see some kind of random communities feature so I can discover new ones.

Most of the stuff I see is memes or US politics that I’m just not interested in.

The lack of smaller niche communities that made reddit more than a news and meme hub. Some exist but most are either dead or not even made yet.

Worse still those communities are probably the most effort to start for the least gain, but those were a big reason I used reddit for over a decade.
