I made a chart of how many people read any given pair of webcomics, against how many would be expected to read that pair if they chose what to read entirely at random, and, it's colorful and pretty and I'm proud of it 😁
Stuff outside the Poisson iso-lines is statistically significant. To the left, more people read the pair than can be explained by pure chance, so there's probably some reason to believe they're related. Pairs to the right seem like people who read either avoid the other one.
