Google Search on a misnomer that, to my perception, is becoming far too common. The real phrase is “perfect complement” with an ‘e‘. But I encounter “perfect compliment” nearly every day now.

The same idea could apply to the articles Wikipedia. Instead of taking “in the same film” as the relation, you can take “is linked to by”. We’ll call the “Kevin Bacon number” from one article to another the “distance” between them.

I wanted to find the centre of wikipedia, that is, the article that is closest to all other articles (has minimum closeness).” (Stephen Dolan)
