The “feed view” feature lets you customize YouTube‘s homepage when you are logged in. YouTube orders chronologically the videos from all the other sections you’ve selected: featured videos, promoted videos (which can’t be disabled), videos from your subscriptions, recommendations, friend activity. Unfortunately, YouTube’s promoted videos can’t be filtered, recommended videos constantly change and there’s no actual feed generated by YouTube. You can obtain a feed that aggregates the latest videos from your subscriptions using a Yahoo Pipe.
