I answered a question on LinkedIn asking about the difference between Web 2.0 and Web 3.0

I cited the common understanding that the terms are hype and not based on any substantive metrics - and my usual quip predicting that Web 3.0 will come with the maturation of neural brain wave controllers such as Emotiv Epoc headsets.

Tae Hyun Moon liked my answer so much he asked permission to excerpt it on his blog, along with nine other answers.
