Via Scientific American:
On 23 Feb. 2011, I posed a question to my "followers" on Twitter: "If you stopped ‘doing social media’ (Twitter, FB, LinkedIn etc.) would anyone notice? Would your input be missed?" I received several replies, the most cogent of which came from University of Oklahoma geoscience Ph.D. student Jefferson Chang (@jeffersonite), "It's not my input that I'm concerned about, but the information that I wouldn't otherwise receive."
