Felix Salmon on Bitcoin

It is a very good piece, although I fear by adding this link I will get more media requests to comment on Bitcoin.  Here is the best set of sentences I have read today:

…bitcoins are an uncomfortable combination of commodity and currency. The commodity value of bitcoins is rooted in their currency value, but the more of a commodity they become, the less useful they are as a currency.

There is, by the way, no current way to short Bitcoin.
