Question: Is the BTC exchange price (On Mt. Gox, etc) a good indicator of growing demand for coin on a larger scale? Or is it merely a snapshot of demand at a specific moment in time? Or does it not give any clues?
If bitcoins were only used for commerce, and were sold as soon as each transaction confirmed there would only be a small valuation of all the coins combined (e..g, well under one dollar USD).
So the entirety of value above that is speculation that in the future the amount of commerce including bitcoins will be much higher than it is today. While some are today thinking $11.75 is a good spot to unload, others are thinking the exchange rate goes higher.
So a rising exchange rate is only a good indicator of future expectations, not necessarily a good indicator of growth in current demand.
This is a chart that is a pretty good indicator in the growth of current demand:

But there's no way to know if there's further upside, or if Bitcoin's traction will increase enough to justify current expectations.
It's purely speculation.
