In 2004, Frank Warren started an art project called PostSecret. He asked strangers to mail their secrets they'd never shared with anyone to his house. The game plan was to put the few postcards he received into an art exhibit… but he just kept receiving more and more. Frank started a lo-fi blog where he shared a handful of secrets once a week. Now, PostSecret is the largest advertisement-free blog in the world and he’s received more than a million postcards from strangers. -- SOCIAL: @postsecret on Twitter and Facebook. | www.postsecret.com @brandenharvey on Instagram, Twitter, Facebook & Snapchat | www.brandenharvey.com.
