So is Cyworld a sign of things to come in other countries? Companies such as MySpace, which was recently bought by Rupert Murdoch's News Corp. (NWS), are busily trying to create similar virtual societies in the U. S. and elsewhere. And SK execs are hoping to repeat their success in other parts of the world. They plan to launch customized versions in Japan, China, Taiwan, and the U.S. by yearend. Is your avatar ready?
