The project is centered on a brief study about the Internet-based social networks. In order to get first-hand data, a small application will be designed, programed and distributed, with the final goal of observing its distribution dynamics, the behavior of its users and its theoretical economical viability. Accordingly, the student has to become familiar with Facebook and the tools it offers for developers-users, make use of them and be able to project, code, deploy and analyze a small application, which can raise a minimum social interest.
