I've started mining ether with Genesis Mining about 2 weeks ago. I've had a couple of small payments since signing up.
In the long term, I'm not sure how profitable it will be. I've paid about 1 Eth for a 2 year mining contract at 10 m/hash. The hash rate is increasing due to people using my referal link.
