Just got a thought ~ So I got a startup which I am aiming to grow to a million users spending a fortune on paid advertising online, but the cointent solution helps me get a small cashback by not helping me grow my business! Or I pay a high traffic site to display my ad, and they sign-up with cointent to make their site clean, eventually the hits/impressions decrease and no one pays the site for displaying their ads! and they re-think they made a mistake signing up with cointent in the firstplace! Could some-one please explain how this model is going to sustain/ be successful?!
