After a decade of watching the Internet change everyone's lives (including mine), it never ceases to amaze me. The Internet gave me a job and a career. I pay my bills online, follow stocks, buy DVDs and books, argue about the Celtics with complete strangers on a message board, send streaming video of my kid back home to my parents, get almost all my sports information, keep in touch with dozens and dozens of family members, friends, acquaintances and co-workers every week. There's always some new way to kill time. But YouTube ranks among the greatest Internet developments ever, right up there with iTunes, Napster, free porn and e-mails with "Vegas?" in the subject heading. For instance, last week I was watching a YouTube clip of Rowdy Roddy Piper smashing a coconut against Superfly Snuka's skull on YouTube and marveling at the magnitude of the moment: Not that it was a defining TV moment of my adolescence, but that I only needed to type in the words "Piper's Pit" on YouTube's search engine and the clip popped right up on my laptop. Unbelievable.
