SK Communications runs Cyworld, a hugely popular social networking site in Korea. Or, as the article describes, “The company does not operate Cyworld — its customers do.”

SK Communications president Yoo Hyun-oh attempted to nail down the will-o-the-wisp that is Web 2.0, the much-touted next stage of the Internet. “Web 2.0 is philosophy,” Yoo mused. “At the center of it are openness and sharing through which many nameless individual users make Web 2.0 more powerful.” He will be a keynote speaker at the Web 2.0 Conference in San Francisco in November.
