Thanks everyone for your input. 

That would be really interesting to find the traffic of spendbitcoins, but I bet if I could get my hands on that data, I couldn't get it fast enough to detect market swings. 

The problem I have with Google Trends is that the resolution isn't high enough.  You can only see interest by month.  This makes it more difficult to detect interest before the price starts raising.

I am trying to design the site as simple as possible so everyone understand what all of the indicators mean and how to properly read them.
