Maybe, but I don't expect most websites to track which videos I have watched and I don't want to need to create an account or somehow sync my watch list across devices. So I just use my feed reader for that and it works excellently. > My feed reader's intended use case is to following a large number of slow moving feeds like personal blogs This is also the majority of my feeds. While I agree that a few items falling through the cracks is a big deal I would still prefer if they don't. But I think the morale of the story is that there is a huge set of ways that people use RSS Feeds. They are a generic system for distributing updates and it is hard to make quick fixes that work well for all of the wide variety of use cases that people have.
