https://bitcointalk.org/index.php?topic=84112.0

everything is open source so you can see everything that is happening, there are no secret magic, no cookies, it is all controlled by you, which is one of the core values of bitcoins. Cause with a web site as soon as the hosting becomes too high or it isn't worth his time you lose your faucet time tracking source with my extension that can never happen!
