This is a much more real life experience than chatting with a keyboard in a chatroom.
Only private cam sites allow you to broadcast yourself to the cam model.
The most recent significant improvement is the full screen expand option found a the upper right of the chat area.
This because there is a human interaction between you and the model.
This means when you are broadcasting yourself through a webcam to the model and the model shows herself to you on webcam.
A channel chat room allows the room host to view all chat room participants webcams and the room participants may view only a large broadcast stream of the room host.
The one-to-one chat room option allows two persons to view each other using large broadcast stream format.
All these performers combined makes us the biggest live cam site on the internet (thousands of webcams online)!
