Varying user's sense of value, it is getting more important to deal with users' individual needs and value standard, when designing a product or a service. Such needs or value standard would be not only formed by their own attributes, but also affected by an interaction with other users. To analyze such interaction among users and emergence of needs and value standard, and to build a model of user which could imply such interaction and emergence, we observed a complex network structure which is composed of users. This paper reports an outline and a structure of real network instances, Weblog network and social networking service, applying complex network analysis. Then we propose an information diffusion/spreading model on the complex network, and experiment it by computer simulation on the real users' network.
