C# SDR

We are holding our C# SDR meetings this week in Redmond with some of our best customers
who come from a wide variety of backgrounds. The discussion is great and the feedback
we're getting will help us build better products that help solve real-world customer
problems. Keller blogged
about this yesterday, but in reading his post, I realized I'm not sure what SDR
stands for.  I always thought that SDR stood for Strategic Design
Review, not Software Design Review. Wikipedia's
only definition for SDR is a type of RAM memory, Whatis.com points
to Software-Defined Radio and AcronymSearch finds
five matches with the closest one being System Design Review.

If you know the right answer, let me know :)
