Bitcoin? Uh, no thanks. Just need a way of putting a little real money into some service, and then painlessly transferring a little of it into sites when they ask for it (and I want to pay it). "This page costs x" or "stream y minutes of video for x" or "24 hour access to this site for x" etc. Sometimes the solution is out there but it's not been made simple enough or is not adopted by enough high profile sites or whatever. There's flattr, a popular one, apparently, although I've never actually seen it used in the wild. You'd need a paywall but where the wall is only a few pennies or a fraction of a penny high. My objection to a paywall is not the need to pay, but the need to sign up for a site ("great, another site i have to trust with my credit card details") and the high cost ("you want £20 now for a months access? I only want to read 1 article"). You'd not buy anything in a real shop if you had to pay up front, in each shop, separately, before you'd even decided you wanted anything from that shop.
