Ask HN: Would an open source podcast rating/review system help podcast discovery

It seems that the sluggishness of apple podcast software combined with the splintered nature of the podcast player market makes rating/review/recommendations of podcasts really difficult. As such there is no central place to find individual episodes of podcasts based on your listening habits/tastes which is frustrating.

Would a non-profit, centralized aggregator of ratings and reviews (with appropriate privacy controls) as well as potentially a recommendation system be useful?
