You are totally right!
But, I know, if I share some quality information on my social media (with explanation, proves, and so on), and do it once or twice, it'll have more effect than if I was posting every day.
It's like selling Avon or Oriflame (or Amway, whatever): if to post about it every day, people get annoyed and no one orders. But if to post once a month, showing some useful info, perheps, one finds clients.
And the biggest and most effective work is personal communication: if we drink beer with a friend and I tell about Steemit, and show my account, that person will be much more interested than if he/ she got known about steemit from my instagram. I belive so.

I think the best if I advertise kinda powerful account of my own. Then people will want the same, might get interested.

My plan is to wait until the end of the Diary Game and then to see what happens, how can I invite ppl to Steemit.

But, as I said, I'm absolutly ready to help with your contests organizing.
