Hey pesst,
I think its a good concept, but definitely going to be tough to bring in revenue.
I find the site lacks a bit in design. A sleeker design such as the one on keep-tube will make the site seem more legitimate. Have you looked at how the competition is monetizing?
One easy add on would be adding a button saying "chat with a live girl" which you can link to one of my livebucks sites. Conversions might be tough without a ton of traffic though.
If you want to discuss it, email me
