That's the way to do it!

We went to preview night of a play at our little local theatre last night. The play itself was fun (The Big Bang, the story of two guys trying to recruit investors for their enormous Broadway musical about the entire history of the world), but what really charmed me was that afterward, the director and artistic director(?) sat on the stage and solicited the audience about what worked and what didn't. That's right, they got people to pay them to be held captive to provide critique!

I gotta get me some of that. I wonder how you could modify that to work for written fiction?
