I'd like to see a dedicated web page that details all the differences between ESRI's web APIs (silverlight, flex, and javascript). Like many developers, I believe in using the right tool for the job and can go between these languages easily. If I don't need to spend time reinventing the wheel if Silverlight already has the widget/sample I want, I'll use that. That said, I love the flexibility that anyone can pick the language that they already know and work with it, but I bet some of us would rather just pick the one that will make our work the easiest. :-)
