A while ago, I have received recommendations here for non-news podcast in colloquial German. I am also looking for language-themed podcasts, focusing on vocabulary, grammar, and style for the German-speaking public (i.e., not for DaF learners).
Background: The success of books like Eats, Shoots and Leaves marks a resurgence of interests among English speakers in linguistics, language, and style. There are quite a few English podcasts on these subjects. The most well-known probably are Grammar Girl, Lexicon Valley, and A Way with Words. I know that Zwiebelfisch has enjoyed great popularity and came out with Der Dative ist dem Genitive sein Tod. I was wondering if there are any language-themed podcasts along the same lines.
