Openbook was a Facebook-specific search engine, built upon Facebook's publicly available API, which enabled one to search for specific texts on the walls of Facebook subscribers en masse which they had denoted, knowingly or unknowingly, as being available to "Everyone," i.e. to the Internet at large. Both an avowed parody of Facebook and an Internet privacy advocacy website, it was built by San Francisco website developers Will Moffat, Peter Burns and James Home within a few hours on May 12, 2010, and received nearly six million page views in its first two weeks on-line from over a million people in over two hundred countries. The website received extensive media attention from, among others, the Wall Street Journal, NPR and ABC News, including international coverage.
In May 2012, the website was moved from its original domain youropenbook.org to openbook.org. In July 2012, Openbook was shut down due to legal reasons, and openbook.org has reverted to a foreign exchange website. Another website, http://www.bing.com/social, as well as Facebook itself, provides the same capacity to search Facebook pages for a word or phrase.
