Matt Hill is the CEO of Shopit.com. Shopit is like eBay for social networking sites. According to Matt, Shopit is now the fastest growing e-commerce application on Facebook. EBay has had a lot of fraud problems, and a lot of people don't like using it anymore. After interviewing Matt, I wrote about eBay's problems and how Shopit could take over this space here. I think the model will take some work to implement properly, but they have a good team and a space with massive potential, so keep an eye on Matt and his team. Matt also talks about his involvement investing in a couple of successful companies including reunion.com.
