Online confessors are like flashers. They exhibit themselves anonymously and publicly, with little consideration for you, the audience.... One online confessional, though, breaks the mold. At PostSecret, found at postsecret.blogspot.com, the confessions are consistently engaging, original and well told. How come? The Web site gives people simple instructions. 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.

The blog isn't as great as the article suggests but it does highlight just how easily it could be to start a winning blog if only you had a good idea and the gumption to see it through. Anyway worth a look.
