I am amazed how few people in the US know about bitcoin and even fewer understand it.  I work in a very technical field which allows me to travel and I am constantly surveying technical folks of all ages what they think about bitcoin.  I would say only about half of the people have even heard about it, of those about 80% of the folks say stay away or "if you can find someone to give you real dollars for bitcoin, do it!"...

I've also noticed that bitcoin does get news coverage but it is almost always buried on the major media outlet's sites.  Most major headlines are very negative so I can't blame Joe Public for shying away.

All in all, we are very early in this game and I'm excited to see opinions sway in favor of bitcoin in future months/years.

I personally think there will be an "Aha moment" whether it be a killer app or a market correction where big banks move to bitcoin as a store and the sheep will follow quickly.  Just a matter of time but the train is still in the station at this point in time.
