Glaser interviews WSJ.com managing editor Bill Grueskin about changes in the past year to the mostly pay-to-view WSJ site. As the Journal prepares to switch to a smaller print edition, Grueskin discusses WSJ’s plans to “be more aggressive online — especially in the area of online community and engagement.”
