Trust is social networking’s next big challenge and next big opportunity. Openness can be a good thing, but like everything it has it’s contexts that it is valuable for and contexts where it does harm. Think of the world of openness we live in now with social networking sites. While they serve a purpose and provide value under certain contexts, we are aware that there is also value in confidentiality. The balance of the need for openness and for confidentiality comes down to trust. Many of the social networking sites grew big fast because they were open and people saw the size of the networks as the value. While this can be valuable, providing an experience that can be trusted in openness and confidentiality will be how social networks grow in the future. Platforms that are only open and cannot be trusted, will shrink as users become more educated.
