Yeah I see what you are saying.  I think the first step is to simplify the exchange process.  I had to read up on how to buy bitcoins and tbh it was a total pain to get some.  If you could just buy them direct from a bank account in stead of having to wait a week or pay a hefty transfer fee then that would go a long way to better adoption.  That will be the first barrier to cross.  The second will be transaction speed.  The average person does not want to wait so long for a transaction to go through.  They are used to credit cards and instant money.  Third there needs to be some advantage that bitcoins have.  Why would the average person use bitcoins in stead of dollars?  If I get ripped off using my CC then I just call them and have the transaction reversed.  BTC has no such thing.  It needs to have an advantage for the average person and not just us.
