This is my favourite article about Bitcoin to date, and properly describes one of the main ideas I wish Bitcoin detractors would come around to.

The secondary functions of money - store of value and unit of account - are precisely that...secondary. You can't have the secondaries without the primary (see: gold). I sort of wish the OP wouldn't have made the characteristic of money as being a medium of exchange out to be a "oh well money is also this". The problem is that the press got a hold of Bitcoin for it's secondary reasons and drove the eyeballs to that without defining the problem to begin with: our medium of exchange, globally, is broken.
IMHO, Bitcoin adoption curve is taking exactly the course it should be: the exchanges that are at most threatened by poor inefficiencies ("third world") are seeing the most benefit. The first world doesn't have a problem moving money because there are solutions...they just cost money. Third world doesn't have solutions. Once they all see benefit the "first world" will adopt. It won't happen overnight and it shouldn't.
