Razorfish‘s Shiv Singh blogs at Going Social Now about a couple of interesting studies released by the agency:

“Digital Mom consists of two companion studies. The first study, conducted by Razorfish focuses on how digital moms are adopting social and emerging technologies. The second study, prepared by CafeMom–the largest social networking site for moms– concentrates on the role that social media play in helping to inform purchase decisions, among other key trends.”

Another interesting batch of data emerges from a report on Social Media Measurement: Widgets and Applications, which shows:

“… that the more deeply engaged someone is with social media, the more likely he is to make a purchase. More specifically, there’s a noticeable difference between those who engage with widgets through media versus those who are referred by friends.”
