Tim Anderson just posted a fantastic interview with Scott Guthrie from Mix UK 07. They dig into a lot of cool technical details about Silverlight, WPF, and ASP.NET, which is why I think it's so valuable. Tim does a really good job of asking fairly technical questions and Scott is always good at giving meaningful responses that appeal to both business-types and tech-types.
There's some strategy stuff in there about Adobe which is interesting. Scott breaks down the developer market and makes what I think are valid points about the various developer communities. The best stuff is on the technical side however. Tim has a great summary of the Microsoft/Novell agreement and how it relates to Silverlight. There's also some cool stuff about how the CLR is being managed now that it's cross platform and how the compact framework (the CLR for mobile devices) fits with Silverlight.
