In the UK only one person I know has actually heard of Bitcoin and the others who haven't I've tried to educate them on the subject. I then realise I need to be educated further on the subject myself to stop the head hurt. I feel the spread of Bitcoin has been through word of mouth and has grown organically, imagine if it was marketed like PayPal or some of the other financial institutions.
