Give podcasting full respect by making it a search heading.
Bing should do it too. Also DuckDuckGo. In fact all search engines should make podcasts a search heading. Simple as that.
If they make podcasts a search heading, they’ll make podcasting too big a category to fracture into a forest of silos.
This doesn’t mean Apple, Spotify and others can’t continue to offer subscriptions and other forms of aggregation. Or that ListenNotes will go out of business. (Though that’s a risk. Remember Technorati?)
