I think it's a little more complex than that. This is how Synereo works as I understand it:
I'm a content creator, and I publish an article on Synereo. I put 100 AMPs on it, and that means it will come up on more people's feeds. You see it, and receive 1 AMP for reading it, paying you for your attention. You decide that you like the article so much, you put 10 AMPs back on it, propelling it further so more people can see it, but I also get a percentage of the AMPs you put on it.
Yes, you can pay people to read things, but it's going to be more cost effective if you create things that people want to read and share, as opposed to dumping a bunch of money on something that nobody wants to see anyway.
