The interplay between social media and e-commerce is an emerging business model. Social recommendation, as an important part of social e-commerce, plays a key role in affecting consumer judgement and decision process. Despite increasing number of technical researches, the research in the role of design affordance of social display features in the context of social media driven e-commerce is still missing. Anchoring on signaling theory, we develop and validate our hypotheses using a series of online experiments. Our findings indicate the presentation of friends-based feedback can induce higher purchase intentions than presenting the crowd-based feedback. We further propose that this relationship is moderated by the temporal distance. Specifically, when the temporal distance is short, recommendations from friends are more persuasive than those from the crowd, whereas the opposite occurs for users at the longer temporal distance. Our findings have important implications for research and practice in designing effective recommendation systems.
