Facebook Common Ground:

I really liked the general idea of seeing how people would act when they had knowledge but might not think it polite to put forth their knowledge/common ground directly. The different ways people approached it, from acting like they hadn't seen the Facebook to casually asking questions that would lean towards information they had gleaned from Facebook, was fascinating in what is says about how people determine the most polite or best way to act in conversation. Really interestin stuff. Great work.

Emotion:

Really interesting project, guys. I find the idea of emotion as a contagion and the differences in how accurately people can detect others' emotions in different mediums really fascinating. I agree with the general sentiment that it would be interesting to do the experiment with friends, and see if they fare better. All around, great idea and great analysis.
