This new version is really doing great, best way to figure it out is to give it a try yourself:

Key thing is we push a new girl for free to the user's desktop every day till he buys or uninstalls, if you think about it that's a lot of exposure time compared to the average website.
It works best with softcore traffic, anything babes, solo girls, nude and mainstream like screensavers, wallpapers etc. On porn traffic, it won't do well as a main sponsor, but it's a good add on to any page to monetize the part of the traffic who likes soft stuff.
Last but not least Mr Will, it's one of the very few content that can't be found on p2p or tube sites
