[21:08] Useful find of the day: on any YouTube channel you'll find the
externalId in the source code, which you can combine with the string
https://www.youtube.com/feeds/videos.xml?channel_id= to get the URL of the channel's RSS feed. So in case of the FSFE the URL would be
https://www.youtube.com/feeds/videos.xml?channel_id=UC68ldbHwL_-5qzETqOaAMWQ (since they apparently chose not to set up a custom channel URL you'll find that the URL to their channel itself also includes said external ID). That's neat, because there are a handful of interesting channels I'd like to watch, but I don't want to set up an account for this.
