Man, DTube seems amazing! I could certainly see myself uploading some videos, eventually. Being rewarded in STEEM for videos is awesome.
Having said the above, yes, I know I can link YouTube videos inside Steemit posts, but after a few misunderstandings here and there I am not really sure I want to host videos on YouTube. And there is no real way to embed videos from other providers (DailyMotion, etc), so DTube looks like an interesting project! :)
