Pretty neat. For me, I’d love to see something like this for YouTube. Perhaps it’s just my bad habits, but I find I generally spend time on what I’d consider quality entertainment (that is, I don’t regret having spent time on it) for Netflix, Amazon, Hulu, and the like.

YouTube on the other hand, I’ll usually start with something I consider quality like 3b1b and then end up watching much more of forgettable things I regret. Whenever I go to resume a video on YouTube via browsing my history, I’m always in shock of just how much crap I’ve watched.
