Interesting idea.

I recall Steemit, maybe in the whitepaper (?) saying they wanted unique content to be found on google or other search engines, and it gets people to come here exclusively.

I don't see the advantage of having your own personal blog, which has an extra point of access for the same content. Once the distributed content system gets up, then I would see this as more viable to be able to interact into steemit, from the outside blog as well. But for now, that's missing, and the double content thing which might not be favorable... dunno... But interesting idea.
