Postsecret blog: 21st century confession

Via century old technology.

"Mail your secret anonymously on one side of a 4-by-6-inch postcard that you make yourself. That one constraint is a great sieve. It strains out lazy, impulsive confessors."

I am not sure how "anonymous" the mail is, since you have to go out of your way to escape the postmark, but still a cool idea.
