28,000 MMS messages — multimedia pieces of communication like photos, videos, and voice communication — are sent into the world every second, and cell phone companies record much of the metadata that travels with them, like location, identity of the receiver, amount of data transferred, and the cost of the transmission.

We actually know more about everyday life in Sumeria five millenia back than we do in Europe fifteen hundred years ago. The Sumerians recorded everything on stone or clay tablets, most of which were discarded after use with no thought for posterity. As it happened, the clay tablets proved remarkably resilient and so archaeologists and scholars have found and decoded hundreds of thousands of them. This data exhaust gives a rich view into trade, worship, life, death, medicine and almost every other aspect of the Sumerian's world. This is a big reason why I'm so fanatical about opening up data sources.
