The following video is part of our "Motley Fool Conversations" series, in which director of community and social media Greg Robleto discusses topics across the investing world.

In today's edition, Greg takes a look at a new player on the social media scene, Pinterest, that is growing rapidly from unexpected demographics and changing the rules of social media engagement. This new way of interacting, the interest-graph, is not prominent on Facebook and LinkedIn. It provides a new opportunity for public companies with strong brands and highly visual products to reach a captive audience that is more than willing to advocate on the company's behalf.
