I don’t think you need to go full Reddit to replace it, just an interest in a niche and a desire to host a website.

The struggle is that it takes more than love of a subject to bootstrap a community. I could see someone broadly succeeding by building modern forum software alongside an optional discovery platform that links forums together. I know there are federated platforms out there, but I think a large portion of them have lost the thread of the user journey in attempts to meet the technical challenges of federation.

Reddit's charm is that you can easily discover brand new communities and it's zero friction to get involved, you find a new subreddit and start interacting. No need to remember the new site or set up new credentials. A bunch of different communities adds all that friction back in.

I agree with your first statement. For years, I have been working on a website/app/community platform to support learning and debate about the productive uses of nuclear energy.

My vision is more of a combination of the best of Reddit, online courses, blogging, photos, video, learning games, and simulations. More of a slice across many different types of app, tuned to the topic at hand that interests me. It's fun to work on, even if my progress is slow.

Reproducing r/nuclear seems like a nightmare scenario. Lots of arguing. Tough to control the tone and screen out-dated information. It's the classic problem with social media, discerning the difference between reality and myth. Plus, reading through screaming matches is not a fun way to learn.

Aggregating these smaller nightmarish sites, who wants to do that?
