I saw this posted to Hacker News just now. Looks like it might be the start of something useful. I assume that one can suggest additions (or other edits) by emailing the curator using the address on the upper right of the page.
I’m sure it was probably an accident but sending r/StarWars to the Star Trek Lemmy community feels like a massive troll.
This was more useful list, and certainly a better populated one.

I wish the site was open-source so I could just submit pull requests to add new ones, rather than emailing the creator (they might get overwhelmed by too many emails, multiple people may suggest the same thing, etc…)
Sounds great to me, but I’m not sure how many average people would be willing to learn to use git and get an account at the repo host just to submit update suggestions. It would be nice if the site owner had some documentation up explaining their plans, if any, for how this will operate in the longer term.
This list at the moment is pretty abysmal at less than 10 entries. There was a far more complete list I saw a couple of days ago. Had at least 100 subreddit alternatives.
This was the list I was thinking of
