Data for the podcasts section is coming from Ask HN threads and will share a similar format to Books. I'll tag podcasts as show type (i.e. interview, 2 hosts) and typical length (Tuesdays, 30 minutes) as well as try to highlight a podcast's most popular episodes.
If you'd like to know when the Podcasts section is released, I'll send a notification to the monthly newsletter subscribers. The newsletter is only sent once a month, and covers recommendations from HN regarding a single topic each month, like: systems thinking, negotiation, advancing your engineering career, etc.
