Based on the feed back from many different YouTubers now @TeamYouTube!
YouTube is infact broken. Notifications are not working. And people are getting recommended videos that are two months to two years old.
Youtubers are experiencing a 20% to 30% loss in views.
Don't trust poop tube to send out notifications... Always send a tweet that you have a new video up. It's not a solution but will help views and will also let followers know.
