I've had a great time on the CLR. The main reason I'm moving is for variety. (Although my wife thought changing from CLR to DLR was hardly much of a change.)
I know we've still got some work cut out for us on the CLR Debugging services, but I'm proud of what we've accomplished on the CLR debugging services during my watch. We have some very cool things in the works there.
I suspect this will also have an impact on my blog topics.
