The front page looks fantastic! Unfortunately I can't get @pennsif's interview to play - I'm getting an error message saying that "the media used features your [Google Chrome] browser did not support". However it is playing the other 3Speak videos.
I'd love to know if there's a point of difference from Dtube - is it because it offers livestreaming? Or because you don't have to be a member of Steemit to use it? I'll certainly give it a try :)
