The Limits of EPM

EPM measures people and the most popular podcasts, according to what those people say they listen to. This makes it very good at the current sample size at telling you a fair amount about the top 200 podcasts. Those are fairly stable, but it tells you very little about podcasts 201 to 20,000 in popularity. And it tells you absolutely nothing about podcasts 20,001 to 4,041,596 which represents 99.99% of available podcasts.
