ABSTRACT: Innovation over the past five years has occurred in a wide variety of areas, from more flexible graphics to faster connections to richer communications options. It’s difficult to keep track of the full alphabet soup of innovation on the net (PHP, AJAX, SVG, CSS, etc.) but the latest wave of advancements, and the sites that make use of them, are broadly referred to as “Web 2.0" because of the revolutionary potential they offer to reinvent interaction between people over computer networks.
