Here is current web scheme. Users post information. Websites create ad places using this information and sell them to advertisers. Websites turn ad places to ad and give it to users. Users follow ad and buy products supporting advertisers.
What if we change this scheme and improve it by two simple but very decisive actions. We will give user an opportunity to change rules of ad impressions and choose ad which is shown with his information. And we will take part of money got from advertiser and give it to user.
