Cutting back at the Prospect. The Globe's Mark Jurkowitz today reveals that the liberal American Prospect will soon move from a biweekly to a monthly publication schedule. New executive editor (and former Globe publisher) Ben Taylor -- whose hiring was reported exclusively in Media Log yesterday (okay, okay, the Prospect's own website got there first) -- tells Jurkowitz, "It's a more natural schedule. I think we can do a good job in a monthly format.''
