I find the sweet spot for a good subreddit is between 10k-100k subscribers. Less than this range results in low activity (posts from 6 months ago still on front page) but more than this range just attracts karma farmers, memes, and witty one liners at the top that don't add much to the discussion Of course the subreddit still needs to be focused on a specific topic
