Interesting presentation on social commerce from Matt Moog of reviews site Viewpoints and of “triple bottom line of social commerce” fame (the triple bottom line being 1) Sales and Traffic, 2) Actionable Customer Insight, 3) Customer Loyalty and Advocacy).

Matt argues that four web trends (dominance of search, growth of social web, influence of [e-]commerce and the disruption of media/advertising) make the time right for  social commerce.
