Sure, it's all in the name of promoting a new book, but Vanity Fair has a new interactive feature that allows you answer its trademark questionnaire (originally constructed by one Marcel Proust) that closes each of its issues. It consists of twenty questions-from "What is your greatest fear?" to "Which living person do you most admire?" to "How would you like to die?"-which have been answered by a great many cultural luminaries.Once you've completed the interview, you get a list of the iconic people whose answers most closely resemble yours. For the record, my answers suggest that I'm most similar to Nora Ephron and Arnold Schwarzenegger. Jealous?Take the questionnaire.
