In the last couple of years, I've been adding the HTML/JS/CSS skillset to my stack of required skills and my talks and courses have reflected that change. To my readers who are deep in the XAML stack, this change seems to have come at somewhat a shock to many. I've even been accused by some of abandoning the Silverlight, WPF, Win8, WinPhone folks. This has caused me a lot of frustration because I don't believe that developers can or should only know one possible stack. To reach the full breadth of users, sometimes you need to be able to develop across the ecosystems. In this same time, I've also done quite a number of HTML/JS/CSS talks where I didn't use Visual Studio. Some have conjectured whether I am moving away from the Microsoft stack as a result of the lessened use of Visual Studio in my demos. The frank answer is: nope.
