It's that ease-of-use which has been designers and standards compliant coders biggest problem. modX solved that problem, what more could you want ?
@Starbuck: I was referring to a robust set of add-on components that were easy to use and configure by the technically-challenged end-user. These will start appearing more as we make the developer API more robust and make customizing the manager easier. As a developer, I look for semantically correct API classes and methods when I want to create new components, in the same way that an XHTML/CSS designer might expect to have semantically correct elements and style selectors to work with. A lot of the quality PHP developers out there will look for the same, and that is what I want to attract. So that's what more I want for MODx.

The problem with promoting modX kickass - is that it sounds too good to be true, how fu#ked up is that!
All you need is csszengarden powered by modX - that's the key!
Ha, now that would be the bomb! A one page MODx site with infinite themes to select from. Maybe they'd let us mirror the themes out our own site, and we could blow their minds by adding dynamic CSS options, some customizable content areas to allow themes to define additional markup in the same way the extra div's provide placeholders for additional images used in the design.
Where's our marketing guys!?
