Good analysis. Of course, all of these initiatives are great (and obviously im biased towards one of them). My only comment on one of the three is with DTube. As you kind of alluded to, it does seem that some people who are producing content of "less than brilliant quality" do seem to get repeatedly upvoted whereas a lot of quality content on there goes un-noticed. But then, that is the same all over steem. Hopefully this will change as the platform grows and more great content providers appear on it.
