The site, which started as an experiment on Blogger, was updated every Sunday with 10 new secrets, all of which share a relatively constant style, giving the artists who participate some guidelines on how their secrets should be represented. From June 24 to July 3, 2007, the "Comments" section of the site was enabled. While a comments feature is frequently present on blogs, it had been previously absent from the PostSecret site. Many visitors felt that the new section contradicted the purpose of the site, as evidenced in numerous comments criticizing a postcard in which the author claims to have fed bleach to her cat. In October 2007, the PostSecret Community was launched. Since its inception, more than 80,000 users have registered for the online discussion forum.
