Micropayments are an interesting topic. I don't want to pay 5 cents per article I read, I'd much rather pay $10 a month for unlimited articles, even if I end up paying more than I would with the first scheme just because with the first one, I make a decision to spend money with every click. I know there are projects trying to streamline this, but it really should be as close to the UX of the latter as possible, pay a set amount and never think about how many things I can read.
