I really like the idea especially for things like blogs and so forth. I love the picture of the kid reading that you used but I have some reservations about what you use it for. I think it might be somewhat dangerous to crowdfund or tip for Open Source projects. There's some research in behavioral economics that suggests mixing social norms and market norms is not a good idea. In essence someone is more likely to help you if you offer them nothing than if you offer them 1$ because if you offer nothing the social norms and "help your neighbor" kicks in whereas if you offer them 1$ they apply market standards and think something like "WTF only 1$...GTFO" I think anonymous tips might actually not show this effect not sure if there is any research in that regard. Maybe tipping non-monetary stuff would be better. I.e. keep a counter and once the money to buy item X is reached the guy being tipped gets that. Developer conferences, hardware and so forth are obvious candidates. [A good pop-book on the topic I liked is "Predictably Irrational" by Dan Ariely...he also has a TED Talk on this iirc]
