Possible to an extent. I'm also picky about my subs and I find Reddit a lot better than its public perception would suggest, but some of my interests are still apparently impossible to indulge on Reddit without trading off between a frequently toxic community or dead subs. And I've seen the transition from latter to former happen too many times; alt subreddits like /r/Games used to be wonderful, but now tips into an /r/gaming sensibility more than I'd like. Don't get me wrong, this isn't always the case, but I think it's difficult for subreddits to adhere to community guidelines like HN contributors do because going from obscure to critical mass can happen so rapidly.
