The Internet IS a series of tubes

(via BoingBoing) This is an amazing image charting the Web As We Know It (circa 2007), using the Tokyo underground as a reference. There are some interesting relations implied in the chart, for example, PirateBay is listed as one of the main sites, just as LastFM, YouTube, CraigList and OpenID, which seems to make some sense, but that means that it shares that line with Yahoo, Google, MSN and eBay. Microsoft shares the technology line with PayPal, Adobe, WordPress and Apple. Some others are baffling, why is About.com between Wikipedia and Apple in the Knowhow line? Why is YouTube in the Knowhow as well?

Update: Talking about neat graphical representations, here is a Periodic Table of the Internet.
