Just to clarify what i said

A week after The hard fork, My ETH earnings did not reduced at all !!! (
Mining ETH right now with around 2.8 GH/s)
Your statement "ETH reduced their block reward from 3 to 2 Ethereum per block
SIGNIFICANTLY reducing miner earnings" is not correct! You concentrating on reduced reward, and not calculating the lower difficulty bc the hard fork, and totally left out the delayed difficulty bomb from your calculation :-)
