I think people will not have a problem following the exchange rate, if they were sure that the price was not manipulated.
We have seen transaction volumes exceeding 100 000 for a while now, and the price does not reflect that. {Yes, I know it's not a true indicator but it's one of them}
The exchanges are the weakest link in the Bitcoin chain. {Hacks; manipulation...etc. etc.} We will have to find a suitable replacement for them in the form of p2p decentralized exchanges.
These exchanges are pulling us down, and we must prevent another MtGox fiasco.
p2p exhanges are a myth. Sure, the crypto coins can all be held in a decentralized manner, multi-sig, etc... But the real world financial system doesn't "do" decentralized - for every "decentralized" exchange, there'll need to be at least one person, one company, that isn't decentralized at all, but instead holds all the fiat and transacts fiat as people need.
