It’s been no secret that social network platform Ning has been going through a significant transition in both its leadership and business model in 2010. In March, longtime CEO Gina Bianchini was replaced by COO Jason Rosenthal. And in April, Ning’s bubble burst — the company laid off 40% of its staff and killed off its free service.

And June brings new revenue streams for Ning’s social networks, in an effort to help Ning users monetize their social networks.
