What is said on the Internet is not secret, which some teachers have found out the hard way. With freedom comes responsibility but also the responsibility lies with those that hold and hopefully protect private data and information,
"Information privacy, or data privacy is the relationship between collection and dissemination of data, technology, the public expectation of privacy, and the legal and political issues surrounding them" (source: http://en.wikipedia.org/wiki/Information_privacy).
But when do the lines get blurred, when does information become a tool of power? At the point that power controls information then the production of knowledge is compromised and wisdom becomes dogma. Orwell then is a futurist, double think destroys rationality, newspeak becomes the lingua franca and room 101 becomes the destination for the erudite and the free.
dou•ble•think ('d&-b&l-"thi[ng]k), noun, Date: 1949 : a simultaneous belief in two contradictory ideas.
