Hi. Could you compare popular cam2cam sites and give their pros and cons? I just don't really understand how they differ from each other except for the interface.

For the most part, they differ only in interface. They may also use different methods for counting tokens and gold, but the equivalent value in dollars is still roughly the same. I chat with webcam models from different cam2cam sites, but I like CherryTV and Camsoda the most. This is one of the biggest and most comfortable webcam sites in general.
