the big picture We are witnessing a data explosion. "Everywhere you look, the quantity of information in the world is soaring.According to one estimate, mankind created 150 exabytes of data in 2005. This year, it will create 1,200 exabytes." The Data Deluge. The Economist, Feb 25, 2010. P.S. 1 exabyte is 1 million terabytes.
the big pictureWe are witnessing a data explosion. "we create as much information* in twodays now as we did from the dawn of man through 2003" -Larry Page, CEO, Google *This is mostly lolcats and duckface photos.
