Steve Levingston penned a goodbye to his job as head of WaPo‘s “Political Bookworm” blog. The blog saw its final post yesterday. It’s safe to conclude that the early bird has eaten the worm. But Levingston offered readers zero explanation as to why the publication decided to abandon the blog.

“It’s time for Political Bookworm to close its doors,” Levingston wrote. “The range of books we’ve covered has spanned a wide spectrum: from tiny houses to major trade publishers to renowned university presses. We’ve had heated exchanges and thoughtful conversations — the signs of vibrant democratic life.”

WaPo‘s book coverage has waned in recent years. In January 2009, they shuttered the stand-alone Book World section and moved reviews to two pages within other sections.

Levingston isn’t leaving WaPo. He wrote that now he’ll be “writing for the Post in print and online” and editing nonfiction reviews for the publication.

FBDC asked Levingston the same question as a sole commenter on the blog’s final post: “Why?” Levingston never replied. We’ll update if he has anything to say.
