I was going to donate 5$ or 10$, as I found the whole experiment and write up worth it - especially since the content was available for the masses to pique their interests.
I was unfortunately unable to so through Amazon Payments, as they only accept payments from US citizens at this moment. And I do not want/like to use Paypal.
I would challenge us: What value do did we get out of it?
A dollar? $.50? $.10? $.01?
What we support grows. What relationship do we want with content? Do we want advertisers to control everything?
$.10 per casual view madly alters the equation.
Sadly, solutions like Flattr aren't gaining any traction.
