we at tipjoy are designing a new payment system. If you have any ideas or design requirements for an API, especially for micropayments, let us know: http://tipjoy.com/feedback
I've used both PayPal & Amazon's FPS. I would accept both if only because enough people feel strongly about one.
Unfortunately you can't get paid through tipjoy... Thought about moving your country to a different country where you could actually process payments easier than in the US?
You can get an Amazon gift card, and we'll expand to other kinds of gifts cards. We'll move on to actual cash once we're licensing as a money transfer agent. This will happen soon because we're in the process of raising a round of funding.
I can vouch for Ivan's responsiveness re. API requests. Thanks to tipjoy's Platform API users of my site can now add tipjoy buttons by checking one box.
