Thanks for the feedback! I agree that money does complicate things (doesn't it always?) here. Unfortunately, Dwolla (my fee-free payment processor) doesn't have a way of making transactions publicly viewable (though I'll be making the feature request—thanks for pushing me on this). I've seen other projects use letters from the nonprofits as "proof" of the donations, but since this project only donates a few cents at a time I thought it wasn't worth imposing that on the charities—but perhaps that's not true (since I'm sure they have to write those letters all the time). Bitcoin definitely can make things very transparent, and I appreciate your thoughts around taking advantage of that. I'm somewhat worried about driving away non-technical users with an overemphasis on cryptocurrencies though. It's been a tricky needle to try to thread. Anyway, lots of good stuff to ponder here—thanks!
