In this paper we discuss the quantitative assessment of the strength of weak ties Granovetter’s theory, considering the problem from the perspective of the community structure of the network.

We describe our findings providing some clues of the validity of this theory also for a large-scale online social network such as Facebook.

In detail, we characterized their overall statistical distribution, as a function of the size of the communities and the density of weak ties among communities.
