I listen to a few podcasts on the Relay.fm network. Relay Starts started with me trying to work out how longer it would take me to listen to Upgrade from the beginning. Each show has a RSS feed, which I parse in Python to extract useful info. The code is available on GitHub under the MIT licence.
Currently, the Python script is run as a cron job on a Linux server ever 6 hours. The output is formatted into a Markdown file, stored in the git repository and then pushed to GitHub. Using GitHub hosting, the output is available as a web page at https://relaystats.com/
