PC World recently published an entertaining and thoughtful piece on the 16 Greatest Moments in Web History. It includes The Drudge Report breaking the Monica Lewinsky story, the introduction of webcams, MySpace and even my favorite, Craigslist. Rounding out the top three items on the list are: "When Sergey met Larry," in reference to Google co-founders Sergey Brin and Larry Page's first meeting at Stanford University; "Day one of irrational exuberance," in reference to the day Netscape's IPO created the dot-com frenzy — in 1995 the company's shares zoomed from $28 to $75 before settling back down to $58 at the session's close; And of course, "World wide wonder," in reference to December 25, 1990, or the day the Web came online. It may be a chicken or egg question, but what do you think is the most important day in web history?
