I don't think people move from Facebook to Steem because right now it's comparing Apples to Oranges. Steem doesn't haven't Facebook competitor right now. Steemit is more of a blogging platform.
Facebook is more of a status update, picture sharing, soap box if you will. Sharing short little updates on things that you like. Minds is more of a Facebook competitor.
Maybe someone someday will develop a competitor to Facebook on this blockchain. I'd even like to see a version of Twitter on Steem that had a way to post that didn't show up on your feed, but had it's own separate feed.
I can't wait until the value of this platform and blockchain is fully realized. As you most other top 50 and even top 20 cryptos are nothing, but promises of future earnings in the next bull run with no real tangible value or uses currently.
I honestly think that is one thing we need to do more of as a community is to reach out to app developers on other blockchains to figure out what it would take to get them on this platform. I have a feeling once a few are converted to this blockchain successfully it won't be a hard sell for the rest with the community on this platform.
This is possible but it is going to depend on interface filtering. If people only look at an unfiltered view (steemit.com at the moment) everything is seen. But for example, steemhunt filters out everything but Steemhunt.
Perhaps they pay for the development through the speculation, like steemit inc does. that eventually ends.
