Six degrees of Captain America: some scientists at the University of the Baleares “studied the statistical properties of the network of 6,486 characters in the 12,942 Marvel comic books” since 1961. They found that the network of acquaintance among Marvel characters is “very weakly clustered – about 1.5 times more than a random network. Clustering in real networks is typically ten (or more) times greater than in random webs.” (Naturally, I found the link at a comic strip site.)
