In an email interview with Washington City Paper, Washington Post Book World fiction editor Ron Charles worried about the subscriber rate for the site's podcast series.

Here's more from the post: "There's no concrete deadline for adding more subscribers, Charles says, or even a goal for how many it needs, just 'a general mandate to make sure we're concentrating our efforts on projects that are actually attracting an audience.'" Update: On Twitter, Charles says the podcast needs "about 100K additional subscribers."

Featuring ten minute interviews with writers like Francine Prose, James Ellroy and Margaret Atwood, the show deserves some iTunes love. After Maria Arana retired, Charles assumed podcasting duties at the review.
