The Overcast.fm web interface provides any podcast, and any episode of any podcast, with its own Overcast page.
This page is publicly accessible, and supports timestamp links. So you can share, for example, a link to an episode that, when loaded, will auto-play starting at a specific time.
This is a great way to improve the shareability of podcasts. Lots of times you'd like to share part of an episode without asking your followers to sit through the entire preceding 45 minutes or whatever. Ideally all podcasts would support this functionality on their own sites, but this is sadly still pretty rare.
