Web 3.0

One of the clearest explanations I've come in contact with regarding the whole Web 1.0, 2.0, 3.0 preoccupation comes from Jonathan Strickland at HowStuffWorks.com (See http://computer.howstuffworks.com/web-306.htm).

Before you do that take the Web 3.0 Quiz (See http://computer.howstuffworks.com/web-30-quiz.htm) and see if you can "ceiling out" on the pretest.
