Re: "connect viewers with content they love"
The subscribe feature is actually useful and works.
You can then go to https://www.youtube.com/feed/subscriptions and can see at a glance if there's any new videos from the channels you follow.
Shoot, some of the podcasts I watch are over an hour and a half. Personally I download them and watch&delete them as I have time and feel bored.
