I used my own metric that is based on jaccard similarity. Which in turn is based on "users who posted to X also posted to Y" metric.
That said, there are a few subreddits that are too popular and similarity results were too saturated (/r/videos, /r/funny, etc.) so I did a manual override by looking into most commonly mentioned other subreddits, and sometimes into `about` blurb of subreddit).
Please don't consider these recommendation as source of truth! It's just a fun way to discover other subreddits :).
I'm also very open to change this metric to something else - please let me know if you have any recommendations!
