I don’t know that everyone who uses RSS to follow YouTube channels will actually click on each video. I “subscribe” to (i.e. follow the RSS feeds) lots of YouTube channels but there are some that I only watch a few of the videos.
What would be nice for me is if YouTube would include some of the description text in the RSS feed in addition to the video title. That could save me from clicking through in some cases. The video feeds I subscribe to on PeerTube do that which is nice.
