Rick Byers has started a blog (actually, he's had it for about a week now)! Check out http://blogs.msdn.com/rmbyers/ .
Rick is another developer on the CLR debugging services. He knows a lot more theory then I do, and has the most experience actually using managed code on the CLR debugger team. He’s got a great interest in static tools and .Net language development (which I think provide valuable insight into the debugging space). His first post is a great quiz: “Hello world” in different .Net languages.
