Newbie question here.

I see the unit of measurement Mh/s and Gh/s tossed around a lot, esp. with pools.  I've picked up that it's measuring collective processing power (number of solutions checked per second?), but what exactly is it?

Thanks.

I was reminded about BitCoin at Occupy Vancouver yesterday, perhaps there will be another bump in interest now that Occupy has gone global.  Also, according to Option Stalker (link below), prices seem to be stabilizing. Of course that's really over a period of 7-8 days.

It's stable enough that I'll be offering statistical consulting for BitCoins in the next week, I hope.
