  In this work we present a mobile application we designed and engineered to
enable people to log their travels near and far, leave notes behind, and build
a community around spaces in between destinations. Our design explores new
ground for location-based social computing systems, identifying opportunities
where these systems can foster the growth of on-line communities rooted at
non-places. In our work we develop, explore, and evaluate several innovative
features designed around four usage scenarios: daily commuting, long-distance
traveling, quantified traveling, and journaling. We present the results of two
small-scale user studies, and one large-scale, world-wide deployment,
synthesizing the results as potential opportunities and lessons learned in
designing social computing for non-places.
