It would be similar if you join any new platform. You can post also to YouTube, and say vimeo, and the many others out there. I find it frustrating that I need to go to YouTube for many of the video channels I enjoy. People are creatures of habit . it's going to take a long time to migrate them from YouTube to other platforms.
It's not only the viewers of YouTube videos but also the producers that are stuck in their habits. So, they stay on YouTube in spite of dropping rewards. The bitcoiners that bought into Bitcoin saved early benefited the most. Get into Steemit now and you will benefit more.
What happens on YouTube should be a wake-up call to all YouTubers that they ought to build their audiences on as many platforms as possible to remove the single point of failure problem. Get on viewster, vimeo, videojug and tube.video. Continue posting to YouTube as well but give your viewers options of where to view your content.
