Time is passing and we started to have more and more single page applications or frameworks like new twitter and Sammy.
It seams like it is the next big step, where we eliminate generating code on server side, servers start to be only data providers, all the UI is done on single page using javascript.
I kn ow there is no real definition of Web 2.0 (except using ajax), so I do not except any definition of Web 3.0, I only search for indicators of our evolution of the next big step in application development.
So question is: Is single page application an web 3.0 start?
Note: I know there were questions about web 3.0, but they are old (almost one year for newest).
