You can direct revenue from advertisers to users and if you put it on a truly decentralized blockchain you can also prevent censorship as well as have verifiable privacy related features.
Advertising revenue is not sufficient to pay the users. We've documented this so many times, it is really ridiculous that I've had to repeat this dozens of times. I was the first person to point this out several months ago.

I am waiting to see how Synereo actually works. For me at least, the process calculus mumbo-jumbo technobabble is an enigma at this point. But I don't understand in any case how they expect to be able economically justify this with an advertising revenue model. Perhaps they feel they can much better target ad spending relevance, and thus achieve much higher revenue per user?
