- Interview With Web Guru Tim O'Reilly: 'We're Moving Into a New World'
- Der Spiegel (12/04/06) Stocker, Christian
Tim O'Reilly, considered the father of the term Web 2.0, says he has gotten sick of the term and wishes it was understood as less of a dotcom-bubble-type fad, and more as "this idea of harnessing collective intelligence." He believes that "open source communities create a lot of value," and that programmers should not be, and are not, resentful about not being paid for their work that companies use to make money because they understand the benefit to their reputation. Wikipedia is an example of the way Web 2.0 is built around trust: While anyone can submit an article or make edits, there is a still an inner-circle of users who have proven their loyalty and integrity. He praises online information gathering projects for their attempts at accuracy, given that "anything we do is a selection of reality. That's a great source of disorder in our society." O'Reilly says the "wisdom of crowds" is somewhat represented by Google, which he calls "the furthest we've come toward artificial intelligence," and while individuals still make decisions based on the "quality of results," these decisions, which go against the Google system itself, sometimes turn out to be wrong. Pointing out that the best anti-spam measure is people's ability to identify it as spam, he says, "We're moving into a world that's not just about people expressing opinion--it is really about distributed data gathering and real time intelligence." O'Reilly does not fear the entrance of PR and advertising into sites like YouTube, because the success or survival of such services rest on their quality. When asked about predicting the next buzzword to have the impact of Web 2.0, he spoke of a new magazine he is helping to create called "Make," which will focus on the interaction of computing with the physical world, such as custom manufacturing, synthetic biology, and the democratization of these types of advances.
