I just spent the last few days on vacation in Vegas with my daughter. She set the agenda for the trip, so I spent most of my time looking at cute tigers and hanging out in malls. Luckily, one of the things she wanted to do was very interesting.
At the MGM Grand (where we stayed) is a focus group company that feeds consumer information to the big TV networks. My daughter and I sat in on a focus session where we watched a not-yet-released TV pilot episode called Taxi 22 starring John Leguizamo. During the viewing, we had our hands resting on a dial that we were instructed to move between zero and 100, based on how much we were enjoying the show. As you watched the show, you kept moving the dial up and down based on how much you liked it. So if a scene started to bore you or piss you off, you would dial it down, and if something happened you thought was interesting or entertaining, you would dial it up.
