Utilizing the "uses and gratifications" approach, this study is to explore social networking applications for married bisexual men to secure social support. With the view of use motivation, the results showed that the motivations of easy access and entertainment could be met by using the Scruff, but the sociability motivation was relatively low. The respondents corrected the impression of using the mobile media, but also change the expectations of social networking services. All the respondents would continue to use Scruff although feeling dissatisfied with the needs of social support, but also get back to use personal computers to seek social support by using the "old school" social networks. Instead of using one form of media, the new phenomenon marks the multiple uses of various media forms of social networking services can meet the physical and psychological needs, and the use experiences of respondents re-interpret the theoretical structure of the theory, creating the cycle of exploration and gratification experiencing by an app user during social support searching.
