I think you`re right faucets reward you with so little amounts you have to be stupid to believe you earn some money by claiming the satoshi`s from there. But sometimes it`s even fun to visit these sites and for me it has been a good lesson in how to send and get BTC. How to create and use a web wallet and things like that. It was my start into the Bitcoin ecosphere. And of course it was good out of my perspective that I didn`t need to pay for directly. By the way I`ve made an Account at Mr.Gox the first time when I got in Contact to Bitcoins but never used it cause of the lang period they needed to prove my identity. I`m still happy about that when I see what happend to other Mr.Gox Users.
