There is a bit too much pop culture and "fluff" looking content at a first glance. That might be fine as far as "weird YouTube rabbit holes" goes, but I guess what I was hoping to find might be a little more esoteric and not so much "oh, some celebrity I've never heard of did covers on YouTube."
The amount of content here also makes me a bit skeptical, because a proper deep dive into a rabbit hole requires a bit of curation.
Here's a free idea for you: I bet a Substack page where you put together one "weird deep dive" per week could do really well. It would be fun to see "ah, what did he get into this week" and then have an easy way to queue up the videos for an hour or two of chilling on the couch. It would feel a little more deliberate. Like you picked some random topic and started absorbing it, and then return to the community with a few videos that kind of "overview" the thing.
I say Substack for illustrative purposes here - I'm not suggesting you switch to Substack - but rather that maybe your model needs to be a little more curated. Build a reputation that this is a fun place to go for a random Sunday morning Youtube binge, that every "rabbit hole" on the site will be interesting.
Idk, just my thoughts.
