I am subscribed to loads of channels. Best is when after 3 days of reloading recommendations to find something nice it suggests me a video from subscribed channel (that I have notifications set to "all") from 3 days ago. Whole 3 days it was unable to suggest me a video I told it I would want to see. Its mind boggling. Honestly think scraping the algo alltogether and writing it from scratch could only result net positive, regardless of how broken new version would be.
