I agree that the algorithm is weird.
To start with, it feels like 30% of the videos are videos I’ve already watched.
The rest tends to be a very naive list of things related to the last ten videos I’ve watched including many that were recommended before that I didn’t watch and never will. Often I pull down to refresh and it alternates between two lists and that’s it.
I know recommendations are a complex problem but the results seem very far off from what I’d expect.
