This is a fine UI, I've known about it for a long time, but it is putting the cart in front of the horse. Sure, you can browse a tiny, tiny set of data series.

This is a fine UI, I've known about it for a long time, but it is putting the cart in front of the horse. Sure, you can browse a tiny, tiny set of data series. What the world needs is a unified source of searchable, browseable, and joinable time-series data from government, industry, and NGOs. Then put the fancy front ends on. I've been trying to generate interest in this idea for seven years. I don't know why Google hasn't already done it.
