Web next

Web 2.0 is interesting as it isn't so much a "new" computer language rather a technology. A use of existing methods in a way that is different.

I guess the biggest and most well known use is that of Google and it's affiliates. Youtube, Gmail, iGoogle, Google maps, etc etc. they all make extensive use of Web2.0 technology.

The ability to dynamically update pages on the fly without a postback (ie. a reload of the page) is typically what Web2.0 is all about.

Not only does it look cool, but makes the overall web experience more fluid and quicker. Of course, it isn't perfect and is limited to the capabilities of Javascript, and that of the users computer and browser settings.
