The 'Subscriptions' link at the top left of the Youtube home page only shows the things you subscribed to, just bookmark that.
What I want is it to only show me videos. Now, it also shows shorts, and also now “community posts” which are frequently just self-promotion and useless polls that drive engagement. I’ve started unsubscribing from anyone that uses those features too much. I want videos not “check out my twitch channel” and “want more merch? Check out my merch! Also this is a poll so that you will click it”
One channel I follow got some new “comments from the community” kind of feature, and suddenly posts from anyone on YouTube were showing up in my sub box because they also subscribed to the same creator. All of the posts were image posts that were blatantly rule breaking spam, or comments like “why is this a feature”. None of them were from anyone I intentionally followed. Literally just random internet comments as a huge section in my sub-box. I instantly unsubscribed.
YouTube REALLY wants to shove other content into the “subscription box” because as-is it lets you avoid all the algorithmic clickbait.
