In my article Web 2.0 and Maintaining the Integrity of Online Intellectual Property I discussed what happens when information flowing through the Internet can change between the time it is created and the time it is consumed.
This can be both good and bad. Good aspects include the addition of new information and the resulting rich functionality and utility that can be created. Bad aspects include the possible loss of control over quality and authority as information "morphs" in ways that may have been unintended by the information's originators.
