yes I think things will change when people can more easily buy bitcoins, for sure, but we have to do something about the hacker problem and we need more exchanges.
I don't think it is that easy to get money into MtGox, or any other trading platform, for that matter yet either. I think once that becomes simplified it will be just a matter of time before there is a huge "Spike" with no return like the author predicts. I am just not sure how close we are to that yet. It is fun to think about though.
