E-mail is now officially old school. Outside of work and school, e-mail appears to be fast slipping into the realm of users characterized by silver-haired retirees marveling at just-arrived e-mail pictures of their grandchildren. Meanwhile, young adults and other outriders are turning the Internet upside down. Such forerunners are deploying new tools that are sparking a boom in the number of digital communities where users control content. Yet these same users are quick to collaborate and engage in social networking. This new generation of blogers, podcasters, wiki editors, flickerers, video chatters, and others is driving Internet content and re-defining how people interact.
