She actually doesn't comment as much as I thought. 602 posts in 9 months. 3 of those are blog posts. That's about 66 comments per month. That's not too hard to do.
I read her bio on her profile that mentions marketing, and I think she may just be really a trail blazer. She is building up quite the list of people she can resteem to. I already see in her wallet history people that pay her to resteem their content. So this could be one of the futures of advertising here on steem blockchain and she may just be a trend setter.
Being paid to resteem someone else's content b/c of 12,000+ followers is a novel approach.
I still have to wonder if it was planned or it just sort of happened?
I edited my post and added a link to an interview @stellabelle did with her. She seems pretty humble, and it doesn't seem so much planned out as it just happened.
She seems very down to earth.
