Read techdirt’s take on it here. My tupennies’ worth: people need to be confident of several things before they adopt a system of payment that they’re not previously exposed to:
a) it’s easy to figure out;
b) it’s convenient, both for the transaction and the eventual physical payment;
c) it feels safe.
Micropayments mostly don’t work online because they’re too hassly for what you’re doing. You’re sitting at home, you got everything you need, what is there to make a micropayment for that could make your life any richer? But if you’re stuck in the subway at midnight and need a chocolate bar, or a ticket home, that’s a whole different game.
