Ruined? Not always.

For example, investment subreddits are generally very bad, yet the Berkshire Hathaway subreddit (r/brkb) is able to keep the rot out without becoming an echo chamber:

https://old.reddit.com/r/brkb/

This subreddit has literally dozens of value investor moderators, and the bubbles (cryptocurrency/ARK/Musk) are forcibly excluded.

The result is a forum where Buffett's principles of intrinsic value (discounted cash flows) and moats, etc., are explored for Berkshire and the many connected companies (e.g., Verizon).

I mean, there is not much discussion on there.

A sweet spot is a place where there are enough people to have long discussions but each person is deeply invested in the health of the forum itself.

My point was more about the difficulty in preserving the quality as quantity goes up. If you keep the quantity really low, then sure, you can enforce quality. But, then it feels pointless because there simply aren't enough conversations to engage in.

My favorite subreddit has thousands on comments on the weekly thread, yet I can realize familiar names, have deep conversations while the total sub count stays around 10k. Incredibly strict moderation helps (thanks dang), but it is a thankless job.
