@davidpakman I've been wondering the same thing, albeit with Instagram rather than YouTube. While Instagram was a great platform for me to build a following and release content for about a year, the recent changes to the algorithm and the overall pettiness of people on there (it seriously feels like high school but worse), coupled with Facebook's increasing crackdowns on Instagram business that doesn't directly benefit them, makes Steemit look SO MUCH MORE APPEALING. Really the issue here is with the overall new-ness of the platform. It still has quite a significant learning curve compared to the major-league social platforms, and not a lot of people on it (broadly speaking).
Also forgive the unrequested advice, but when posting DTube videos I usually like to go back in and edit the post on Steemit to include a YouTube link as well (like I did in this blog post for a song I released a while back.) DTube is a young service and still often drops out/takes ages to buffer, so I find that people like to have a YouTube backup link in case the DTube stream is struggling.
