I use Google contributor, but only because I want something like this to succeed. I don't actually like the implementation they have. The biggest thing for me? I can't see where my money is going. At the end of the month, I want a breakdown of where my money went.
I want to know that when I went and visited John Smith's blog, he earned $0.13 from that visit. Contributing feels good when you know where your money is going. It's like a charity - you want to know your money went to a cause you care about. Right now I think Patreon has a better model, but I like the smaller increments that Google Contributor offers.
They do give you a breakdown of where your money went at the bottom of their website (when logged in): https://contributor.google.com
It would be nice if they offered to e-mail this to you once a week/month or provided more detail. Even better would be for them to show some of that information in the place of the ads you've purchased.
