Been using reddit for about 6 years, some of the smaller subs are amazing and I think it comes down to two major things, excellent moderation and community below a certain size (usually).
I've thought about this for a while on and off and I'm not sure how you could scale that up in terms of moderation, some of the defaults do well while others are just a wasteground (I've also wondered if that is partially intentional in the sense of give the idiots a subreddit as a decoy).
I like reddit but it has it's shares of trolls and typical online negativity (which I actually dislike far more than the trolls they at least are easily spotted, the constant negativity wears you down).
