I have similar concerns which is why my planned usage of Steemit has back up plans. Come January I'm going to open up a Patreon to support the blogging effort I'm going to be doing here. So there are two ways you can support me: with traditional cash via Patreon, upvotes and interaction here, or both.
I'm also going to keep all my posts in a separate file system. So that if I need to bail on steemit I can re-post somewhere else like a standard wordpress site.
Last, I work free-to-play mobile games and know a bit about monetizing feedback loops. I've actually setup up a couple of Patreon reward Tiers that involve engaging content here at steemit. The main tier in that loop is a fairly low cost tier. So it's designed to turn low buy-in Patrons into highly active steemit users. And yeah, that's kind of weird.
