So you think it's much more expensive at the moment, right? But $0.10/month means already $100/month just for someone who has 1000 "friends". And that's not a big amount. Regular people on FB have often collected more "friends"… A YouTube account with 10 000 followers is actually quite small. But that would be already 1 000 bucks! Most people on this planet don't earn so much money in a whole month. And this would be just the cost for some smallish hobby account… So even when we take your numbers, it's extremely expensive! How is this going to scale beyond some privileged geeks in the western world?
