Journalists in Washington, D.C., have long been accused of living in a “Beltway bubble.” Their interactions on Twitter, however, show them congregating in even smaller “microbubbles,” says a recent study. The journalists within each communicate more among themselves than with journalists outside the group. That means Beltway journalism “may be even more insular than previously thought,” say study authors Nikki Usher and Yee Man Margaret Ng, journalism professors at the University of Illinois, Urbana-Champaign.
