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.
I use it almost exclusively - I’ve bookmarked Subscriptions instead of any other page. But it does feel like I’m unusual in this sometimes.
About 8 years ago I installed an extension that redirects youtube.com to youtube.com/subscriptions and then forgot the homepage exists.
