Imitation is the soul of flattery, and the engine of Silicon Valley. Whatever can be copied, will be — especially when the copiers are pals. After a redesign, Facebook has made its status-update feature more prominent. It now asks users, "What are you doing right now? A sharp-eyed reader notes that those words are eerily similar to Twitter's "What are you doing?" We wonder if this will pose any problems for Facebook CEO Mark Zuckerberg's newfound friendship with Twitter founder Ev Williams .It shouldn't. Copycat wording aside, no one actually uses Twitter to tell their friends what they're doing. If Twitter updated its site to match user behavior, the question would be: "What are you complaining about? What aspect of your business do you wish to promote? Which URL do you wish to send? What jejune utterance do you wish to share with people who aren't actually your friends?"
