hmm, interesting idea. Take the steemit platform functionality and re-brand it as a 'fake news killer'...other issues include dealing with gaming the system, especially if you have ads that are creating a dividend for coinholders...I doubt adsense would be down for these kinds of 'incentivized' clicks.
I'm pretty against including ads on the platform - definitely want to avoid it if possible. But it comes down to if users will be willing to pay small amounts (like a few satoshis) to authors that provide good content. If that's possible then the platform could continuously attract the best authors and it could be sustainable in theory. What do you think about that?
