Earlier this week Orli Yakuel posted a video Q&A with Eric Schmidt in which he defines Web 3.0 as:

“My prediction would be that Web 3.0 would ultimately be seen as applications that are pieced together [and that share] a number of characteristics: the applications are relatively small; the data is in the cloud; the applications can run on any device - PC or mobile phone; the applications are very fast and they’re very customizable; and furthermore the applications are distributed essentially virally, literally by social networks, by email. You won’t go to the store and purchase them. … That’s a very different application model than we’ve ever seen in computing … and likely to be very, very large. There’s low barriers to entry. The new generation of tools being announced today by Google and other companies make it relatively easy to do. [It] solves a lot of problems, and it works everywhere.”

I just came across a post on the SexyWidget blog that shares Nick Carr’s definition:

“Web 3.0 involves the disintegration of digital data and software into modular components that, through the use of simple tools, can be reintegrated into new applications or functions on the fly by either machines or people.”

I find Nick’s definition extremely insightful and very much on the money. It’s funny, we might find ourselves defining Web 3.0 before we are able to agree on 2.0’s definition. Vive le Web!
