Statistic that shows average hours of podcasts released per day/week/month (to help addicts from not subscribing to too many podcasts)
Quick background: Over the years I've accumulated dozens of podcast subscriptions. With changes to my available listening time I still tried to be a completionist and listen to all episodes. After I made some quick calculations I realized that there aren't enough hours in a day to accomplish that, which helped me make decisions about what shows had to go.
This feature could also help with the decision whether to add new podcasts to your feed.
To calculate the length of published episodes over a week it might be sufficient to average over just a few weeks to give a rough estimate.
