Keith Murphy and Mark Schoonover have put together an excellent survey which is already doing good (seeing the numbers they have been clocking). Survey results will be out in the summer issue of MySQL magazine. I feel this is a "must take" survey for everyone in the MySQL community. And do not forget to mention my blog in the "top 5 favorite MySQL blogs" ;-). Just kidding!
Overall, this is the best survey regarding MySQL that I have ever taken, don't miss it. It will hardly take 10 minutes of your busy schedule. A busy man has the time do anything, right?
