On Friday, with the Boston metro area on lockdown, many folks stuck at home were running an experiment in how much information can be consumed at once. I maxed out with a laptop streaming video coverage, iPhone full of tweets, TV blaring footage, and radio providing analysis — all simultaneously. (I’d have been using the iPad too, but was limited by having only two hands, dangit.) While we do live in an era of great access to information, this proliferation of devices only made it that much more obvious that the river of information had slowed to a frustrating drip.
