This is one of my favorite features of The Wall Street Journal. Yesterday they asked Kanye West to name his five favorite restaurants. Usually (and more usefully) some other celebrity is asked to name five favorite books, CDs, or movies.
Five is enough to frame the namer’s tastes. And your chance of learning about a new peak experience is relatively high. Even if you get no useful information, you’ve had a chance to judge a celebrity.
I believe this method of "criticism" will become increasingly popular. The biggest potential downside is encouraging excess winner-take-all behavior on the part of producers.
