The New York Times’ erudite and funny TV/online-media critic and The Hills booster Virginia Heffernan has a new blog, or a new version of her old blog. The Medium is the new iteration of her blog Screens, which was one of the best things out there critiquing anything involving little pictures that move. (I’ll update my blogroll link soon, a process that I believe involves sending in a form by mail.) It comes accompanied by a new weekly column of the same name in the NYT Sunday magazine, and a schmancy TV-in-a-circle logo that looks like it was designed by John Monad. Don’t miss it.
