A neat widget demonstrates the truth behind an XKCD joke: Take any article on Wikipedia, click the first link in the article, and then repeat—and you will eventually end up at “Philosophy.” It even works for “Justin Beiber.” (And, yes, I know, this is a biased exercise because it starts with a pre-chosen endpoint. You might as well say that All Roads on Wikipedia Lead on “Ontology”, because that’s the first link in the “Philosophy” article. But let’s not hate on fun, okay?) (Via FlowingData and Richard Fisher)
