As online social networks (OSNs) have become one of the most popular platforms to spread information, there has been great interest in studying information adoption/propagation patterns in OSNs. In this talk, I will introduce our research work on content adoption and cascades in Pinterest, a popular social curation service where people can collect, organize, and share images that they find of interest. I will also briefly introduce research issues in another type of information adoption and cascades: (i) application adoption and propagation in Facebook and (ii) conversation cascade in Reddit.
