The ranking is based on classic and easily explainable centrality measures or page views, and it is entirely open — all data (Wikipedia and Wikidata dumps) and all software used is publicly available. Just in case you wonder, the most important food is chocolate, the most important band are the Beatles and the most important idea is atheism.

The ranking is based on classic and easily explainable centrality measures applied to a host graph, and it is entirely open—all data and all software used is publicly available. Just in case you wonder, the first site is YouTube, the second one Wikipedia and the third one Twitter.

...I made three days ago a submission with the correct number (3.74). /. couldn't care less. On average the degrees are 3.74, and this is why our paper is called "Four degrees of separation". 4.74 is the distance, which is one more than the degrees of separation. Unfortunately sociologists decided to count the "intermediaries" (so if we are friends, our degree of separation is zero), whereas computer scientists count "hops" (so if we are friends, our distance is one). This generated a lot of confusion. But, just to be clear, no, we did not round 4.74 down to 4; we rounded 3.74 up to 4. :)
