I personally like how it's not too easy to find subreddits, and how it happens mostly trough people mentioning them. It keeps many communities nice and small and protected from the 'lowest common denominator' effect.

Of course this means I may be missing out, but that doesn't bother me too much.

I found a couple of wonderful subreddits by just typing the most obvious subreddit address btw (r/piano ...). And once you have found one subreddit on a topic, most of them are kind enough to put links to related subreddits in their sidebar.

(only example I can think of now is r/drunk and r/cripplingalcoholics, though that's maybe not the ideal choice :-))
