I'm glad you liked it Chris. I did pluck the concept from my very own head (I was stuck in commuter traffic when it came to me.)
As for the survey, there is no denying a natural advantage to MA given my participation here, although I did go pepper the forums at the other sites to try to balance it out a little. (And 10 of those BA times votes came in one day, so maybe there was a bit of organized voting by their core team crew.)
