I had a brief conversation with one of the co-hosts on the GeekRant Podcast that I am on each week (http://www.elementopie.com) and we discussed D-Tube vs. YouTube. He is not a crypto guy, or has any skin in the game for Steem. His observations, however, are salient. He said that he wasn't interested in wading through D-Tube to find good content because 99% of it are stupid, irrelevant and pointless daily vlogs that people are doing just to get money. He's right. Until we weed out this from content and return to quality over quantity, that is going to stop new adopters coming into the community and that reflects on Steem price. If less and less people are curating, up-voting, etc. then it will die a natural death or be overtaken by a rival platform. The barrier to entry for blockchain based apps is low compared to what one would have to do in order to build an alternative to Facebook, for example. Therefore you don't need $10 million seed capital to do this, so Steemit/d-Tube has to be very careful that it doesn't become a forgotten technology because of low quality content. There's a long history of this happening in tech dating back decades.
