There Are No Rules, Jane Friedman's blog, has a nice wrap up of the Penwriters Conference that includes a section on industry trends in fiction (scroll down to see it). Agents are saying "Yes" to romance, dark stories, and the inspirational. "Noish" to mysteries and young adult.
She also has an insightful article on "Writers and Recession" that discusses not only how the economic downturn is affecting writers, but how the publishing industry itself is changing - and there's no going back to the days of print only, newspapers and hard copies. Good scouts should get prepared, boys and girls.
