Micropayments have been tried through third party networks but they’ve never worked. Mental transaction costs is one explanation. People want “free” is probably the other.
Saying "people want free" strikes me as a warped view of the dynamic. It always seems presumptuous to me to think that people would be willing to pay to read what you have to say (or watch your video, etc.) merely because you said it. Most authors online aren't Socrates. Ads on the web are mostly on sites centered around idle distractions/entertainment. People pay exactly what that sort of "content" is worth: nothing.
