according to the article above just over $20 mill goes through silk road a year.
yet going by
http://blockchain.info/stats$26mill of bitcoin transactions went around the world IN ONE DAY!!
so please media people dont think silk road is the main use of bitcoin.. its just 1 out of over 365 uses. if you just base it on the cash volume moving around.
but if you base it on the number of websites theres THOUSANDS accepting bitcoin. bitpay have atleast 2k businesses on their books, along with other webstores with their own personal carts and methods of fiat conversion.
silk road to bitcoin is like what 'walking street' in phuket is to the Thailand baht.
silk road to bitcoin is like what the red light district of Amsterdam is to the EURO.
