It seems that things got worse 4 days ago, when YouTube made Watch History a requirement for showing any recommendations. I couldn't find any mentions of recommendations being broken in the few days before that on /r/youtube.
Anecdotally, in the past week my recommendations became a mix of awful generic videos, with almost no personalization.
Does anyone know what's going on?
