From the wikipedia: "The Internets":

Internets was originally used as shorthand for cluelessness about the Internet or about technology in general[citation needed] but is often used today as an homage to when U.S. President George W. Bush referred to "the Internets" in the 2nd Presidential Debate with U.S. Senator John Kerry on October 8, 2004.

Anyway, even though I am not sure about Bush's thoughts about the Internet, I think this "the internets" concept makes sense. Besides, I have always been crazy about all the names and the confusion about the Internet and the Web.
