What's funny here is that he says that he wouldn't follow a Kim Kardashian tweet, but he would follow a Clay Shirky one, therefore the ROI is lower with her. What he seems to miss is that people who _do_ care about her celebrity enough to follow her will probably get a better ROI from following her links than they would from following a Clay Shirky one - because they have different tastes and interests to him.
