It seems to me the 51% threat is very real, and there's not much we can do about it.  Greed will trump common sense every time. I want to do what I can to contribute to the other 49%.  I'm fully aware that the mining-for-profit ship has sailed, but I'd like to learn how to mine as well as offset the 51% as much as I could.

Anyone got any advice for a noob with good intentions?
