There is extreme bias in the news community (on both sides) because of their investment (or lack thereof)... And possibly a certain amount of attempted market manipulation as well.
In other words, almost everyone writing about bitcoins is full of shit. Take everything you read, on all sides of the issue with a grain of salt.
That's nonsense. The post is a result of applying a particular economic theory of how money works to something that is apparently trying to be a form of money. This theory of money might be wrong in general, or it might for some reason not apply to bitcoin specifically. But to dismiss it simply as "bias" is willed stupidity - it is a way of avoiding addressing the actual arguments put forward in the post.
(The specific theory being drawn on in that post is called Modern Monetary Theory; it isn't generally accepted by mainstream economists: https://en.wikipedia.org/wiki/Modern_Monetary_Theory )
Austrian Economic theory comes closest to this ideal.
If you had to read just one article I'd recommend http://unqualified-reservations.blogspot.in/2011/04/on-monet...
But if you have the time you could read all his articles on economics conveniently collected at moldbuggery.blogspot.com (under economics)
I see it every day. One of my coworkers used to be into Bitcoin and owned a fair number and then decided to donate them away when they were still a few dollars a pop. These days he can't stop making predictions about how Bitcoin is going to fail and how it's all a bubble and ponzi.
It's unbelievable how some people are unable to deal with their cognitive biases.

Economics is like quantum physics: if you claim to understand it, you don't understand it. Let the experiment play out, and caveat emptor.
Bitcoin would be much more encumbered if it wasn't relevant enough for the pundits to pontificate on it.
Let those of us who are interested in furthering the Bitcoin economy do so unencumbered by pundits.
