We study a simple model of information propagation in social networks, where two quantities are introduced: the spread factor, which measures the average maximal fraction of neighbors of a given node that interchange information among each other, and the spreading time needed for the information to reach such fraction of nodes ...

... Further, from the computation of the spreading factor we observed that there is a non- trivial optimal number of friends which minimizes the danger of being gossipped that depends on the size of the network and on total number of acquaintances in it.| spreading gossip in social networks, 2007
