PhD student Chenhao Tan created an online tool that predicts which of two differently-worded versions of a tweet will get more retweeted. The website, https://chenhaot.com/retweetedmore/ , has been discussed by CBS News, The Washington Post, Fast Company, and the Daily Mail. The underlying technology is based on joint work with Lillian Lee and CS PhD alum Bo Pang.
Fast Company had this to say: "It may not exactly be a writing guide on the level of the classic The Elements of Style, but as a guide for getting noticed online here in 2015, it’s certainly not bad."
