The title of this piece doesn't adequately reflect the fascinating methodology it contains. The 538 team uses latent sentiment analysis to create a kind of algebra for subreddits, i.e. r/running + r/weightlifting = r/fitness. Politics aside, it's (IMHO) well worth the 15 minutes it takes to read. I'd love to see HN readers more experienced with the methodology take it to task and see what shakes out.
