Frank Warren's PostSecret is a long-running community art project that lets anyone anonymously mail in a postcard containing a personal secret, which then gets posted online. To date more than half a million secrets have been sent in from all over the world, and today Warren will be discussing the project in an Ask Me Anything (AMA) over at Reddit. He's kicked things off by posting a picture of the massive pile of postcards he's received over the years, and community questions are already starting to pile up. The AMA officially kicks off today at 2PM EST, and you can head on over to the source link below to submit your own question or simply read up on some of the PostSecret founder's own secrets.
