I've noticed the stability as well.  I'm quite happy about it, widespread use as a payment method will only happen if people can count on the price staying stable for at least a few days until they can get it out of bitcoin.  I'm a bit worried about the state of the exchanges for a few reasons, not the least of which is that they seem to be mostly dependent on LR staying good, and the thread about LR possibly going to hell has me worried.  There  is still bitcoin-otc, and bitcoin2cc, and bitcoin4cash, but all of those services seem like it might be difficult to use for even medium sized businesses.  It would be nice if ExchangeZone would add bitcoin to the currencies they support.
