My younger son wants to spend all his time on Club Penguin and Poptropica—virtual worlds for the under 10 set.
My wife, who could barely turn on the computer two years ago, is a FaceBook addict, connecting and posting and embedding videos of a dog rescuing another dog in the street.
My new job search is aided and abetted by not just job boards, but meta-search sites that can look across multiple boards and bring everything (well, not EVERYTHING) to me tied up in a little bow. Similarly, I no longer need to search Orbitz and Travelocity and Yahoo Travel for the lowest rates...a site like Kayak will look across multiple sites.
Today, it's Twitter and Facebook and YouTube. A year from now, those individual sites will probably be replaced by aggregators that bring all of your content on one screen, unpdated constantly.
Daunting yet exhilarating.
