In its infancy but it has begun, an official RTC blog with product group involvement. http://blogs.technet.com/rtc/
I will continue this blog as it represents the support aspect of our product but I expect to help contribute to posts on that site from time to time also. Thanks for your patience and I hope that you provide the feedback to make it a useful site for your day to day work but also to help you receive a better big picture.
