There are two different podcast listening strategies (which informally seem about equally utilized). 1. Download and listen to every episode of a podcast. For many this would be something like Grubers. Listeners typically keep a much smaller number of podcast subscriptions. 2. Read the title and possibly the show notes for each episode and if it sounds interesting download that specific episode. My listening habits are very much in mode one here, but for something like software engineering I think it's likely to be much more the second. By producing so much content and on so many topics they optimize their chance of getting at least a download a week.
