I get your point, that the subject matter here isn't worth downvoting. It's like arguing whether chocolate is better than vanilla.
But I would say that failing to describe a podcast and why you like it (or specific episodes) is poor communication. It would be like a thread about food and someone saying, "Italian cuisine is great. It's delicious." I know nothing from that type of comment about what makes Italian cuisine distinctive and what attributes stand out for the commenter. There are a number of comments like that in this thread.
