On the "exabyte front", I'm not remotely convinced that (a) those statistics are true or (b) more importantly, the quantum leap in additional "information" reflects much more than an explosion in useless bullshit.
How many exabytes consist of the Kardashians, the Octomom, John and Kate, and whatever else fills the 2000 channels on my FIOS? Do you think the patent or the exabyte statistics actually reflect scientific advancement?
