I hope that we are not going to get ads that are financing Steemit.inc This going to lead to more centralization, dependency on Steemit.inc and also like you said unfair if they get the major peace of the revenues.
A decentralized network like Steem needs a decentralized approach in regards to advertisement. I think @dclick is trying to accomplish that. Steemit.inc should do fundraising, create payed services and get more effective and productive. They are a company and should act like one and not be de[endent on the reward pool of the Steemblockchain.
