Yeah, I feel like for 'right now' it's best to post to youtube then embed to a Steemit post, so you can potentially double dip on the monetisation, without paying the DTube author fee, but there'll ultimately be this tipping point where enough users are regularly hitting up DTube for more video content that it will be worthwhile just to post to that platform.

Definitely seems like the team behind Dtube are going to be able to tackle any challenges that could threaten their growth.
