This is very good to hear. As a relative newbie to gridcoin, I was starting to get worried that maybe I hooked up with the wrong coin.
I've only hung around this long by telling myself that my power consumption is going to help the world...though I was having a bit of an ethical dilemma recently when I considered that maybe my electrical usage from a coal plant was hurting more than my contributions through Boinc was helping.
It's a hard calculation to make. I wonder if that calculation has been done anywhere....and now I'm back to searching Google for answers. sigh
