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.

While Pinterest may be wonderfully disruptive to our understanding of social media, it is boosted by the even larger revolution in how mobile is changing how we use technology. To better prepare investors for this new revolution, The Motley Fool has just released a free report on mobile named "The Next Trillion Dollar Revolution" that details a hidden component play inside mobile phones that also is a market leader in the exploding Chinese market. Inside the report, we not only describe why the mobile revolution will dwarf any other technology revolution seen before it, but we also name the company at the forefront of the trend.
