One way to limit comments

Quality control (or, if you prefer, troll control) is an ongoing problem for online publishers who invite comments from the audience. Maybe we should take a lesson from this confessional site that Sarah Boxer reviewed for The New York Times:

Online confessors are like flashers. They exhibit themselves anonymously and publicly, with little consideration for you, the audience. Browse some of the confessionals on the Web: grouphug.us (a simple log), notproud.com (organized by deadly sin) or dailyconfession.com (where you can barely find the confessions for all the promotional stuff). You can see for yourself.

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.
