Reading 30 books a year, is that too much?

I mean if podcasts and books were siblings and I parented both of them, podcasts could beat the shit out of books, and I would still side with him (or her). Even though I'd know very well that the latter is making a structured argument, but the former is just more fun. It has a sense of humour, a personality, but also occasionally lies and makes absurd arguments for attention. But hey! At least it keeps it entertaining and fun in the house. Books can be entertaining too, but often have that snobbish "I am always right" side to them. And most of the times they are right! Until you read one of those self-proclaimed guru's book that is basically just his or her opinions. No actual research behind it, nothing to prove that the methods prescribed actually work. Just a bunch of opinions. Some really controversial ones at that.
