New slideshows on social media and social interaction design

I've posted a couple new slideshow presentations to my site here and to slideshare. This time I threw in some graphics and I've attempted to be as economic with prose as possible! I have one on the conversation dynamics of Yelp.com, and more theoretical one on the Psychology of Users of social media. I'll soon post one on user competencies with social media, and then one on the disruption of markets in which the social web has influence.
