I've been iterating after getting feedback from early users so it's time to be in front of more eyes -- I just put it on Product Hunt 🎉.
The product is still early, and curation for Podcasts is harder than I thought -- I've whittled down the original data set by like 2MM entries (there were 4MM originally) and there are still podcasts that don't belong/are stale/not real (and make search worse as a result).
It's very hard to find a balance between making sure small useful podcasts are seen and spam podcasts are taken down.
Of course, if you know of a podcast you love that isn't there (or should be higher up in search/is placed badly), you can suggest it!
