If anyone hasn't yet read the book "Digital Gold", I highly recommend doing so.  It's an awesome book that talks about the beginnings of bitcoin, who the early adopters were, and how things came to be.

I guess digital gold is a decent term for it, but I think it sometimes gets people confused and there are so many who then start to ask the question, "bitcoin or gold", which is not a legit question.  They both serve different purposes and IMO have a place in anyone's portfolio.
