Many companies use Yammer to drive innovation and especially idea generation / development within their company. They often learn that it is fairly easy to recruit people for the Yammer platform which lets employees share and connect with coworkers in a private, secure enterprise social network.

First, I think we need to divide the approach into three key elements: Awareness, Facilitated content and User-generated content.
