Is this what you believe faucets do for new people? I think when earn a few cent's it will most likely turn them off to BTC. They might even associate BTC with pennies as that is what they would earn.
I would much rather somone read abut bitcoins and understand them. Even mining with a few dollar usb stick is good as far as learning about BTC. I would say a block erupter usb stick would teach someone more about BTC then a facuet. I don't see faucets as spreading knowledge.
End goal of a faucet is to make money for owner, that is true of any faucet.
A USB mini-miner used to be educational, when it could produce dust above the payout threshold of many pools. Now, it's hard to get sufficient dust or even shares at the current share difficulties set by pools.
That's what were talking about is education. I said the usb miner would be better at helping someone learn about btc then a faucet.
I just don't see a faucet as a good educational tool. And yes this and faucets cause dust. If you do micro payments that will happen.
