This is a really interesting post! I think there's a little survivorship bias. As Product Hunt grew 2015-2017, users posted old projects of theirs which were already popular and successful.

My guess would be that URLs for the categories eliminated after that period (eg. Books and Podcasts) are more likely to remain stable and available, even if the product was a flop.
