I just discovered Middlecoin.com. Seems like a pretty cool idea. Anyone use it? Is it reliable? Do you feel like you're getting your hashes-worth?
I'm giving it a shot right now actually. I'm throwing 2.2mh/s at it. With LTC pool mining, I'd typically get about ~.5 LTC/day - I'm going to give middlecoin 48hours and see how it does in comparison.
