Any Smalltalk ethusiasts out there?

A couple of days ago I ran across the web site of a guy who is building something he calls Vista Smalltalk. I know absolutely nothing about Smalltalk but what piqued my interest was this description of what the guy hopes to accomplish. It's all about programming WPF and potentially WPF/E using a designer (IDE) which runs inside IE7. Any comments from Smalltalk enthusiasts would be welcome...

"Fisk's goal is to influence people ready to consider Smalltalk as a potential option to Microsoft's XAML-and-C#-or-VB.NET approach to building rich Web interfaces using Windows Presentation Foundation. At the same time, he sees Smalltalk as a useful alternative to the recently touted - highly touted, in fact -- combination of XML and JavaScript known as Ajax [or Atlas]."
