I have noticed that there is a lack of knowledge about how Bitcoins are being, specifically how much Bitcoin users spend on goods and services. I have made a very short (to make it free!) survey that asks a few questions about why users are purchasing Bitcoins, although I am especially curious how many goods and services they buy.
Insights into these questions can hopefully lead to a more stable exchange, because the Bitcoin 'economy' can be measured.
