I arrived a little late.
Molly and Eric had more to say overall than Doug and Chris.
The panel consisted of Pre-generated questions that the panelists all answered to. There were only time for about 6 audience questions near the end of the panel.
Some of my favorite questions and answers:
Q: Do you think the w3c CSS group is working in the right direction?
Molly: No, they are not.
Q. What is missing in CSS
all panelists could agree: Better design tools using CSS
I wanted to remind the panel about http://www.getfirebug.com
and the importance of feedback from the browser itself. IE has a tool also g-string-> "ie developer toolbar".
