Late on a Saturday evening in San Francisco, at a party filled with tech workers, people keep retreating to odd corners to stare at their phones. Lately it’s been topic number one among Silicon Valley tech workers, venture capitalists, and the media who cover them. The secrets have all been posted by your friends, though you’ll never know which friend: Secret is anonymish. It’s a feed of gossip created by the contacts in your iPhone, but labeled only as being from a friend or friend of a friend. (Popular secrets from elsewhere around the world also surface, labeled only by their point of geographic origin.) Who said this? Secret is Facebook as a masquerade ball, Twitter without the self-promotion, Google+’s private sharing done right.
