Web 2.0 deosn't mean anything, you're correct by saying this, but it is a Concept, just like Ajax.
Ajax was first conjured up in 2005 and it stands for Asynchronous JavaScript And XML. To say it isn't new and improved is not entirely correct.
Most people tend to just host the files on their web server and the user HTTP requests this data. Ajax uses an Ajax Engine that sits between the end user and the web server to allow greater interactivity.
The greater interactivity and decreased load times it offers surely "helps sites" does it not?
I agree that it was wrong for me to say that it was the new and improved Javascript, its not. It's merely an improved way of using Javascript as a backend for this Ajax Engine which will improve interactivity and decrease load times.
The best article to read about it is located here:

But to say that it doesn't websites is a mistake and a huge understatement - if you could offer your users faster load times and a website that will respond almost immediately due to Async. communication, you'd do it.
