I personally use Path and love the "neighborhood" alerts which periodically post to Path "Nathan is in Downtown Austin", "Nathan is in Barton Hills, Austin", etc. This system is very elegant and seamless because it posts directly to the social feed without any effort.

From the landing page for the app I'm unsure of how this app works, or what purpose the shortlink serves. Why not make the app link to Facebook, Twitter and other social networks and just post neighborhood information automatically like Path does? (Or maybe if they have privacy concerns with the press of one button.) This would be much simpler, easy to explain, and would doubtlessly be well received by those whose social networking apps don't have this useful feature of Path built in.
