Who looks at the old charts?

One thing you might do is have some sort of calendar format where you have links to older dates in a table instead of a drop-down list. The long list can be a bit difficult to scroll through and keep track of where you are at the same time.

Something else that I think would be really cool is if you could look at monthly and yearly historical data also. Of course, that would involve making more pages and adding the data together for those pages. I'm sure you have way too much work on your plate as it is...
