Please take a look at our new site Vbuddy, here:

Every web site has its own network.
Network members (employees, students, etc.) are authenticated, so there are no fakes.
Webmasters can promote their sites and make money through ads in their network.
Fans can join and participate too.
Social voting promotes great content, and buries crap.
Privacy controls let you control who can view your profile or communicate with you.

Feel free to ask if you have any problem.
