Privacy & Confidentiality

People are creative, even if they don't think so. Given the chance, they will create something new and interesting. However, what they create is usually based on something that already exists, and chances are that it is copyrighted or protected in some other way. Youtube was huge is spreading people's creations around the world. The Soulja Boy song that used Disney characters for the artists was clearly based on protected material, but the makers of the video still used it. While there are positive (appearance of Disney characters in new, interesting way) and negetive (Disney characters associated with un-family friendly material) effects, Disney didn't take any clear actions.

If people use mediums such as twitter of facebook, they need to accept that everything that they type when using the services, will not be private. Facebook recently updated their terms of use to say exactly that; user's pictures, updates, comments, etc, can be used by Facebook and sold to third parties. Although I don't know Twitters terms of use, I expect them to be similar. These services are only private and confidential for the people who run them.
