Yes, I found that odd as well, no plan to listen to 15 min podcast on a web-page when Im just trying to quickly learn something I need to know to fix my code. Though overall the aesthetics of the site are nice, very clean look and nicely organized.
Content designed to answer individual questions (eg StackOverflow) is often different in form than content designed to provide comprehensive education like college classes.
That's poor strategy when creating developer docs, no one wants to listen to a 15 min podcast when they come to a page to learn something or find an answer to their question. Most people on website are scanning for relevant information and they don't want to spend more time than needed, that is how good content should be presented.
