Whereas Web 1.0 was about technologies such as HTML, HTTP, and SSL, Web 2.0 is more about technologies such as 
AJAX (Asynchronous JavaScript and XML), XML, and SOA as well as applications such as Flash, Dietzen said. 

With Web 2.0, CIOs and CTOs are wondering how they can improve their own internal-facing applications, said 
Todd Burke, an enterprise sales official at Adobe Systems. Dietzen stressed that boosting productivity and 
cutting down the time users must spend on e-mail will be part of Web 2.0. 

"E-mail and calendaring are going to be killer apps for Web 2.0 technology," Dietzen said.

E-mail can be made more compelling by merging it more onto the Web, he said. Users should not be required to 
leave the context of what they are doing to tend to e-mail, said Diezten. 

He also advised using existing infrastructure for Web 2.0. "Your focus is what's the application look like 
and how can I deliver some compelling value," said Dietzen.
