Very nice, detailed post for new comers. I do agree with most of your ideas about Steemit. I think that making money via Steem is possible, but only if you spend enough effort in writing decent content and invest your time and your money also.
Personally I see Steemit as a way to play out my skill of writing (I'm not good at writing at all), also a way to show to the world my vie ( I love sharing my experience to others).
I also invest in Steem, as a way for a long-term investment, not just a short-term play. I hope that my journey and yours will become greater and more successful than ever in Steem!
