Today, Facebook (http://www.facebook.com) is probably the most palpable example of environments known as 'social networks' or 'Web 2.0'. Social networking sites are platforms that facilitate information sharing, interaction and collaboration among their users. However, Facebook's success is not solely dependent on its capacity to connect people, although this was its initial orientation. The platform's power for sharing resources and linking content on the Internet to user profiles, as well as its evolution towards lifestreaming and microblogging, enable it provide support for complex, continuous interaction experiences and, consequently, to structure collaborative-learning processes. The platform's communication tools, combined with the option to enhance its potential by installing third-party modules and applications, allow members of a community or work team to carry out very diverse activities. On the basis of theoretical underpinnings represented by the socio-constructivist perspective on communities of practice, the Web2Learn work group analysed and assessed the features that enable Facebook to be used as a platform for carrying out collaborative online activities from two angles: technological and educational.

The move is a merger of sorts between two previously competing software-development projects with the same goal. EdX has long said it would make the software it built to power its MOOCs freely available to anyone as an open-source package. And Stanford was working on Class2Go, its own free software for online courses. Now the two software teams will work together and focus on developing a single platform.
