Hopefully it will break the kinds of monopoly which exist in the media. That's one of the main benefits I see in countries like the United States. You could create a Slashdot on Freenet where nobody knows who is behind it, for example. It would be difficult to know what information to trust in that kind of system. I think that is necessary and is advantageous.
People do for the most part trust what they see on TV and what they read in the newspapers.
Certainly people are cynical, but where it matters, people do for the most part trust what they see. People need to learn to question what they see and hear and read. Hopefully this will make people realize that they have to judge information on its own merits. The nice thing about these technologies so far is that it has not been about business. It has been about giving what consumers want.
