One thing that I've seen that's a problem with this kind of thing (whether given out by humans or faucets), is <i>what people can do</i> once they get the coins. You're probably not giving them enough to buy anything with them, so what do they do? Just hold them?<p>If I gave you 0.01 Serbian Dinar, what would you do with it? Maybe look at it, and say that it's cool.<p>What do people get out of faucets? Just publicity?
