In a visually arresting presentation at the Future of Web Design event in New York City, Elliot Jay Stocks dissassembles the Web2.0 “look” very effectively.  Stocks makes some very good points here - I’ve had to deal with clients who only understood the very superficial aspects of “Web 2.0.”  

Before talking about any other aspect of a site, it should be a basic understanding that a basic catalog on the web isn’t going to get more hits just because it’s shiny; it has to be built with search and end users in mind, something that a reflected logo and beveled edges aren’t going to do on their own.
