Ask HN: How do you discover great podcast episodes?

I'm willing to spend 5 hours per week listening to podcasts. Not every episode of a podcast is of the same quality, and ideally I'd like to listen to only the best 2-3 episodes from each of ~100 podcasts.

(It would be even better to only listen to episodes that are most relevant to my specific interests, but let's put that aside for the moment.)

Given 100 podcasts, each with ~100 past episodes, how can I get the best 2-3 episodes of each, so that I can just hit 'play', instead of spending half my podcast listening time choosing an episode and/or skipping a few duds?
