As difficult as it can be to get seen here, I think Steemit has better and more workable options to deal with that. You've listed most, of not all the strategies that I can think of off the top of my head. Genuine interaction and thoughtful responses make the world of difference. Consistent quality posts add to that. And the various groups that offer network support help take it that step further.
Great writeup for newbies (and even us not so newbies) for pushing ahead with our Steemit strategy.
And thanks for the mention :)
When I write how tos, I try to give as many actionable steps as possible, knowing I never cover them all, that's why I never run out of things to say! Thanks for the comment, come back any time!
