Site:
The Upper Floor
Reason: It's an unusual combination of bdsm/fetish paysite plus multiple live shows each week that's not being offered by other programs. Tube sites may get the clips from the shows but can't get the interactive part available to members. One of the best converting and retaining paysites so far this year. I'm averaging more than 14 cents per unique sent there and almost $80 per signup on revshare.
