It’s a Website, one I look at regularly, described as follows by its founder, Frank Warren:
PostSecret is an ongoing community mail art project, created by Frank Warren, in whch people mail their secrets anonymously on a homemade postcard. Selected secrets are then posted on the PostSecret website, or used for PostSecret’s books or museum exhibits. Frank also tours, doing live PostSecret shows all over the country. He shares secrets from the site on a large screen that enables the audience to see them, and answers questions. (Videos online of the shows are worth a look.)
New secrets are posted on Sunday, and I usually look at them on Sunday. Sometimes the secrets speak of, or reveal, severe mental health issues, and thankfully the site has a suicide prevention aspect, a link to suicide hotlines, etc.
That’s not where the fascination is for me, though; it’s the sharing of secrets that are, first, something never shared before, and second, true (no way of assessing either of these, but for me and I imagine, most Post Secret fans, if it’s plausible, then it’s true, and as far as never been shared before, who knows?)
