yes sir paparodin that is a great plan, effectively getting double work out of each post, except the exclusively Steemit posts like you said.
The only way that I know to monetize a blog besides selling something on it directly, is to grow it until you have a large audience or followership and then Google will allow you to put ads on there for similar themed products and you get paid whenever someone clicks on one of the ads.
The big blogs make really good money that way and have lots of ads on their blog.
Those are the two I could think of as well. Since I make mostly book related things, I could use amazon affilates or something like that to offer the books that I have read and wrote about. Not sure how well that would be taken in, but I am willing to give it a try.
well sir I think that would work great as long as you had a large following and I have a feeling you will!
