I am reading an interesting article, The Internet that Facebook built, by Michael L. Best. I am not a Facebook user, but the following quote in the article from a book by José Marichal is interesting and makes one worried:
José Marichal, in his book Facebook Democracy, defines the architecture of disclosure as Facebook’s purpose-built environment that systematically and in some ways insidiously encourages its users to disclose increasingly personal revelatory data. Facebook invests millions in perfecting this architecture not with degraded voyeuristic interest; it is simply their business model. They capture and commodify a portfolio of these disclosures and sell them to the advertisers.
Facebook’s interests may not be voyeuristic, but they certainly seem to elicit a voyeuristic behavior from the users.
