Not everyone's happy about scientists on social media. University of Liverpool geneticist Neil Hall recently noticed scientists with large Twitter following gaining a seemingly unfair advantage at conferences and in scientific discussions. As a counterbalance, Hall has proposed a "Kardashian index," directly comparing a researcher's Twitter followers to his or her journal citations. As Hall describes it in his paper introducing the index, "I think it’s time that we develop a metric that will clearly indicate if a scientist has an overblown public profile so that we can adjust our expectations of them accordingly."
