This is late, but I'm glad to see you post!
I can certainly understand putting less effort into it. However, I think it's good to keep putting some stuff up on Steemit just as a way to diversity sources of income. Not to mention, although your channel seems safe on YouTube, some day your channel definitely could get taken down, or limited in some new way YouTube invents in the future. It's a lot easier to deal with that if you already have an established profile people know about on another site.
