I agree with the idea and I have given this a lot of thought even wrote a post about it a while back. Being a marketer with publisher experience I know this won't be an easy road/fix but it can be done.

Just thinking about how to track users/(who opt in) to view ads, plus matching contextual ads with users, + allowing users to sell direct ads, + being able to exclude certain network ads, + being able to have user numbers with context to sell to advertisers is going to be a a monumental project.

It will surely make steem more attractive, advertisers will also have to hold and buy to continue advertising hence raise the price. they will also need a presence and reward interaction from users and can create a much more personalised connection which is what we will be moving to as traditional sites start to squeeze influencers and brands reach.

The idea has merit but what I'm afraid of is that the execution is poor. I'd love to be part of a project like this it could be a game changer
