I have a small presence a bunch of places, but Steem just has a huge advantage in that people have built so many tools on it already. Trying to use Scorum or Whaleshares is just immensely more difficult without things like Gina, Steemworld, curation communities, active social Discords, and so on.

So I'm hedging a little bit, I guess, but it's hard to imagine any of those overtaking Steem. Scorum might become its own notable thing because of the subject focus, if they do it well, but it still has a lot of the problems Steem had two years ago. (52-week powerdown times? Really?)
