Today's big news from the IBC2008 conference in Amsterdam was that we will be demonstrating a technology preview of H.264 and AAC support in Silverlight. I know that I can't take all the credit for this announcement but in my role as an evangelist I'd like to claim just a little credit: over the past year and a half that I have been an evangelist at Microsoft, one of my charters is to get product feedback from my customers to the product groups. When I'm giving a presentation (I typically use MindManager, but sometimes use PowerPoint if I have a lecture-style presentation), and someone gives me some feedback, I immediately switch to MindManager and put that feedback into my map. After the presentation, the appropriate product group gets the feedback.
Getting product feedback from "the field" where I am to the product groups is a crucial part of our product development lifecycle. What do you want to see in your next Silverlight?
