As everyone knows one of the major problems with Bitcoin economy is hoarding. The idea of this poll is to find out whether the lack of spending in the BTC economy is mainly due to the lack of acceptance of Bitcoin payments, or is it that people can actually buy a good deal of stuff that they need with BTC but choose not to.
As of now, there are a lot of stores accepting bitcoins as payment for goods and services, so we can weed out the aforementioned factor in this post. Hoarding is indeed the reason why people don't spend much more of their bitcoins. Think about it. Would you spend your bitcoins on buying a piece of clothing and eventually knowing that the price of your bitcoins now will rise tomorrow. So it's impractical to use bitcoins for that matter.
