Please Take This Survey About The Next Edition of My Book and Get a Chance to Win a Prize!

With the new year, I'm starting the process of creating a new and reconfigured edition of my book, Control Systems for Live Entertainment, and I'm running a survey to get feedback from current and prospective readers on several important questions.

The survey will close at 10am NYC time on January 13, 2012 (Friday the 13th!). After that time, I will draw two names at random from those who completed the survey (and provided their contact info). One of the winners will receive a copy of my 2012 photo calendar a week or so after the survey closes; the other will receive a copy of the book after it comes out.
It's only a few questions and should take just a couple minutes. Here's the survey link:

Thanks for your help!
