One thing that I have noticed recently is that some youtube creators from the gaming genre are moving to twitch because twitch stream subscribers are an even more direct way to make money.
YouTube, in the mean time, has a broken DMCA/content-id/copyright claim system - a constant source of complaints with no support channel to actually help.
I find it fascinating how, in YouTube competition, where Vimeo and DailyMotion are failing, Twitch is succeeding because they are simply focused on their strength and advantage, rather than try to just provide the same service with a nonexistant community. And now with Amazon behind them, they have the money to double down on it.
