Hal Varian’s quote “The ability to take data — to be able to understand it, to process it, to extract value from it, to visualize it, to communicate it — that’s going to be a hugely important skill in the next decade” is the topic from this articulate post  at O’Reilly Radar. It examines the many sides of data science – where the data comes from,  how to manage & use it to create useful applications and which companies are doing great work in this field.
