as others have said below, mine was pretty well curated after having the account so long, and it was a nice mix of "vids I missed from people who I watch every video of", new vids from my subs, and random videos related to my interests. I like the idea of just going through my subscriptions in theory but I have too many, so new videos from people who I really lke watching get buried in the feed by videos from channels I'm interested in keeping up with but I dont watch anywhere near every video
