it may be a blow to the ego for a YouTuber or instagrammer with thousands of followers to start brand new.
If they have been demonetized, they have little choice. at least when they start again, their audience that they build is "theirs" as they can move much more easily across the ecosystem, plus leverage multiple applications simultaneously without having to start fresh on each.
STEEM is the place for all of those and anyone looking to boost their online brand and presence.
I think that in the future there is a good chance that the early adopters will be very glad they were.
