Why hasn't an IMDB/Goodreads for podcasts emerged?
A few people have tried to build this (e.g., Podchaser). But nothing has come close to being really successful. What's the hold up? Is this one of those seemingly "good ideas" that's just not that good?
I would like one. It's hard to find trustworthy curated lists of good podcasts
Maybe because books and movies are more static/unchanging in nature? I realize IMDB also does TV but even then many podcasts have a frequent release schedule that outpaces nearly every other medium besides maybe streaming. Because of this, reviews become stale quicker, and some podcasts talk about something different every episode which makes recommendations trickier
Also worth noting Amazon owns both IMDB and Goodreads. Many folks seem to think they're neglected now and not great platforms anymore
Because the IMDb for podcasts is built into the Apple ecosystem. It has ratings, reviews, category lists, best of lists etc.
Is ListenNotes considered successful? I usually go there to search for interview episodes.
IMDB itself already includes podcasts. I think your question is really why you and others don't seem to know that. The Joe Rogan Experience, which as far as I understand is far and away the world's most popular podcast, has 4.5k total ratings. Gen V, which has existed for a month, already has 19k. Podcasts just aren't that popular. But it's nothing specific about the format. Largely informational, non-fiction content, even extremely high-quality, long-running classics, don't get much attention from critics and discussion groups. Nova has been running for nearly 50 years now and has 3k ratings on IMDB, even fewer than Joe Rogan.
Because you haven't built it
Books and movies predate the internet and discussion forums, podcasts are generally discovered near platforms that they use for communities already. Also, books/movies usually being published more properly (ids, canonical credits, companies behind, etc) is a more obvious "database", if you look past the ratings
Fundamental reason is that books/films is an art.
Something that belongs to eternity.
Something that people have always been collecting.
Podcasts are just entertainment to fill the time, air. Like radio.
Who cares or ever cared about collecting radio programs?
