A 5 minute presentation I gave as part of a group project on Social Network Analysis in March 2014. Here we look at how (and if) social networking services have had a sizable impact on the way influence ripples through a network. Thanks to N. Christakis et al, Bakshy et al. A full bibliography and a more verbose explanation of the ideas and work behind this presentation can be found here: http://bit.ly/1faqcTG
