This is the perfect time to transition folk from YouTube as they seem to be upsetting an awful lot of people right now.

Also, I think the Dtube interface and quality of the videos is excellent. The sense of community and quality of the interactions here are way above YT etc too as you mention.

Mobile apps are the next (needed) step for uploading etc but overall I see a hugely bright future for the Steem ecosystem. Now is the time for Dtube.
