I mined it the first day it was announced - didn't have to sign up and was hitting several blocks a day with only 100-110 kh/s. At around 800 coins mined, that is when the difficulty shot up and I mined for 3 days straight with nothing. So I packed it up and will just hold the coins to see if this goes anywhere. As far as I am concerned it is a simple marketing ploy...but who knows.
