Some people have argued that Web 2.0 is really about how webmasters employ AJAX. That’s one view. I wouldn’t say the only view, but it’s not far off.

So what is AJAX, exactly?

AJAX stands for Asynchronous JavaScript And XML. It’s a programming language designed to make Web applications work more like desktop applications. That would be useful, right?

Actually, it is quite useful. And this will likely become a greater necessity in the future as the Web continues to grow. Facebook, Twitter, and to some extent even Google, have driven demand for more Web applications. The proliferation of Web apps will not decline any time soon. It will only become greater. That makes AJAX a much more powerful language than it has been in the past.

Application development has emerged as one of the leading and most important aspects of Web design. The right Web app can make your website much more powerful and profitable, not to mention popular.

The rise of Cascading Style Sheets and Extensible HTML (XHTML) are also significant developments. But the point is, they are developments. And they are fairly recent developments. Web developers will have their work cut out for them in the near future as more people come online and interact with Web applications. Users will expect websites to load as fast as Web apps and that won’t happen without the use of AJAX. So I believe AJAX is going to become even more important than it is now.
