I generally line up on the "Worse is Better" side of things, so it's rare that I'm critical of development tools that appear to be working. As Laszlo has dived into its DHTML port, though, we've been looking at the existing open-source frameworks -- especially at their class models -- to see if there's a standard we can follow, or even a useful bit of code to pick up. I've been a bit disappointed in the way that the various Ajax frameworks treat fundamental object model of the Javascript client that's running in the browser.
