Relation between seeds’ position in the mesoscale and final cascade size. Color-coded z-P planes to assess whether the modular structure of the following/friend network places dynamical constraints in the growth of cascades (left: ‘grassroots’; right: ‘elections’). A first clear result is that when local leaders ($z>2$) precipitate information cascades, these tend to be more successful. More interestingly, connector nodes ($P_i>0.6$) also succeed quite often, suggesting that a node’s position in the mesoscale can sometimes play a more important role than a rich connectivity.
