+1 Leave the speculating to the speculators, or risk being fleeced by them. The only trouble is that they will continue to set the value of B and affect us anyway, at least until B becomes the unit of account.

Right now, even when we spend B for goods and services, the underlying value is set in mtgoxUSD, and most merchants immediately buy fiat with our B, because they have to pay their suppliers, expenses, and taxes in fiat. They also have to do it to avoid losing their profit in gox pump-and-dump exchange rate crashes (aka "corrections" in Bitcoin)  that we see again and again.
