This is totally genius. The lesser of two evils I admit when compared to pay-for-content, but a pretty good gimmick. I think the model of paying for things in essentially data is totally revolutionary. Its been implicitly done for so long, and we've become desensitised to it - if its as simple as me lending a click with no further disruptions I see that a fair trade, and its a currency I'd be happy to pay with.<p>In the same breath I hope its implemented sparingly, and future iterations don't fall too far from the tree, its one of the few things I've seen that could also seriously disrupt the flow of the net. Having to click one of those, and fill out a CAPTCHA would seriously get on my nerves and stem the smoothness of browsing IMO.<p>There's definitely a startup or two to come out of this space.
