The Web is an extraordinarily dynamic medium that is growing in size and complexity at a furious pace. Web pages already number in the billions and roughly double each year. The contents of the Web are largely unstructured, which may make finding specific information a considerable challenge. However, once you develop some skill at navigating this realm, you'll reap considerable rewards. Surfing the Net can become habit forming, and as your proficiency increases, the challenge may well be knowing when to stop.
