You can use it to kick your cam girls to the top of the site in some cases. It has a motivational purpose to give the cam girl the idea that there is an opportunity in her room to generate some people into members. But if you speak about the System itself, they released 2.0, I have seen the demo on the summit last night. And that system is pretty cool, it is worth to give it a look.
I would say, definitely worth trying out. Hit me up on Skype if you want to have an experience from Studio side.
