I think it's true that this forum is dominated by people who are obsessed with the idea that Bitcoin mining should be a guaranteed ROI, and rail against anyone who gets in the way of their God-given right to free money.

I mine for fun. I hope the coins will cover most of the hardware costs, but I don't delude myself into thinking that ROI is particularly likely. Glad to see I'm not the only one.
