If you have never heard of, or been to PostSecret, you should definitely give the website a visit. Hand made postcards are mailed to the creator of the site, Frank Warren, and each week he shares a few on PostSecret. Each postcard contains a secret that the submitter has never shared with anyone.
You will see all sides of humanity, sometimes shocking and other times humorous. Frank has received a lot of publicity lately and was recently featured on the Today Show. He has published books as well and some of the proceeds he donates to suicide prevention organizations.
Check it out, I don't think you will regret it.
