Testing the strength of weak ties theory in small educational social networking websites

Most face-to-face interaction networks are structured as predicted by Granovetter´s dasiastrength of weak tiespsila theory. This paper seeks to verify whether friendship relation in social networking websites is structured similarly as in face-to-face social networks. This is accomplished by examining the most important consequences of the theory in four smaller educational online social networks. It was found that all of the four networks from three different social networking websites are in complete synchrony with the theory.
