Sharing personal digital information online has been a common activity for many years.

However, the recent rise of sharing economy services has since expanded the set of «things» one can share (e.g., apartments, cars, bicycles, or work tools). How does the sharing of such physical artifacts differ from «traditional» sharing practices of, for example, photos and status updates? This thesis attempts to consolidate the existing body of work on both sharing personal digital content (e.g., social networking) and physical artifacts (e.g., apartment or car sharing), and attempts to identify both commonalities and differences between them. We summarize existing research on diversity of shared content, users’ motivations to share, audience management, privacy & trust issues and user experience requirements. Based on this analysis and additional information gathered from 16 semi-structured interviews with both design practitioners and sharing economy domain experts, we formulate a set of 24

design implications for devising novel sharing economy services. Two of which we test in an experiment with 17 participants using eye-tracking techniques.
