The explanation of how it works is pretty confusing. For instance you say "As an example, if a consumer spends half of his time reading the wikipedia, the wikipedia would get a $4.50 credit at the end of the month." Does that mean that the service costs $9 a month or $10 because you've removed 10% for the free pool? If so why do I have to figure this out from that bit of text? If this is just an example amount then a better explanation like "Say a user pays $10 a month, and they spend half their time reading wikipedia, then at the end of the month wikipedia is paid $4.50 from that user."
I would remove the formula on the "how" page. That seems like something you might need to change later. Perhaps say that producers get a share of the revenue provided by users' subscription fees that is proportional to the amount of time each user spends on the producer's website.
It seems to me that you should separate the explanations for producers and consumers. Consumers probably don't care about how the producers get paid, they just care about what content is available and how much it will cost them a month to access it (yes I realise you're still in the finding the content phase and this may well be your plan, but the site currently has text clearly directed at consumers). Producers on the other hand will want to know in detail how much they can expect to make a month from this service. Also the front page is giving me mixed messages. On the one hand "Support the sites you depend on, without lifting a finger.", on the other "Start monetizing your web traffic today. Login". Sounds like you're talking to two different people there. Should I not login if I just want to access content?
The iframes in the examples are pretty horrible, but that's just my opinion. I would prefer a link to an example.
