We considered possible sub-categories which we could allow for Concertos and we want to test out how much interest there would be in a podcasts category. Hence, we've added it Please keep in mind that we're going to evaluate the interest on the whole category to see if there's even enough interest that it will become a permanent category on Concertos. I think at least 25 podcast torrents in 30 days would be a fair start. So for now the podcast category is in a beta-phase.
