I consistently hear people on YouTube complain that the subscribe button doesn’t do anything for viewers, now that channel notifications are controlled by the bell. But it does do something: it puts the videos from that channel in your subscription feed, which is readily accessible on all versions of YouTube. So why do people act like it doesn’t exist? I think it’s super convenient, especially if you’re subscribed to a ton of channels and don’t want your notifications feed flooded with new videos.
My theory for the apparent need of “click the bell for notifications” is not that videos don’t show up in the subscription feed but that most people just use the home page to get informed which does not show all content. My subscription feed worked without a hitch and not a single missed video since it’s inception. I strongly believe most people just don’t know about the subscription feed.
