Indeed a good participation post. I agree that steemit help us Alot in learning. And writing skills is one of the best skill we learn through steemit.
We also can easily work on our English. I see you are doing nice job for promotion of steemit. Twitter and Instagram is good, I prefer Twitter for easy promotion.
Facebook is also a nice platform for steemit promotions. It allows us group system, pages and much more facilities to get promoted anything.
