*sigh*.  Do you really think that normal people will EVER understand fractions?  The answer is no.  It will never happen.  NEVER.  This is why we need to move the decimal place.  The wider public will never accept a bitcoin that is even worth $15, much less 15 million.  Bitcoin cannot succeed unless the decimal point shifts.  The decimal point will move, the question is whether we will do it soon enough.  The price of bitcoins will drop to a nickle.  Are we going to be the ones to do it, or will the market do it?
