I want to see more content on topics of code organization, and strategies for teasing apart an application's requirements to produce modular, encapsulated, loosely coupled components. I'd also like to see content that disabuses us of the notion that JavaScript has to be all about the DOM, and that steers us away from DOM-centric coding practices when they don't make sense. 

Finally, while I know you are a jQuery evangelist and while I know that Microsoft has a partnership with jQuery and thus this may be a tall order, I'd like to see more content about other libraries. Dojo's data API, YUI's testing tools, and the MooTools inheritance system all come to mind. We do well to learn from the kinds of problems other libraries are solving, and the patterns they are using to solve them.
