Some summer sauce: This free tool uses jaccard similarity coefficient (fancy words to say 'chances of overlap') to gauge the similarity of one subreddit to another. It's great for subreddit discovery, but if you know me, you'll start to see how this can map out a similar-interest graph (like that drop down option on Meta when stacking interest targeting ). ??
