This all sounds amazing and I can see the core of it is addressing that bleed of value going out of steemit without much coming in, very forward thinking. Some of this article is kinda above me as I'm focusing on being a writer of stories, rather than a student of blockchain. But, one thing I see in this idea which I feel might be handled better is:

Most tutorial makers are not good in promoting their content. This is where we will help them by indexing their tutorials and doing direct promotion on the front page. For this we will probably ask a small fee or beneficiary rewards from them

My reasoning behind my opposition to that is purely a personal opinion based on what I would think if I was looking for a platform to publish a poetry tutorial, for example. I would be seriously turned off to have to pay to share my knowledge. But there needs to be quality control, I see that. I think the rep system you're proposing could do that along with assessment of potential tutorial contributors to keep rubbish of the site. I don't know how feasible that would be logistically though, just some thoughts ;-)

I also found what you said about steemit authors posting/promoting their work outside of steemit interesting. I've been waiting for someone to develop an app that will post automatically to a wordpress site when you post on steemit. I stopped publishing on my wordpress site years ago and now that I've learned how to post on steemit, I have forgotten how to design a post on wordpress so well. I'd love to start posting to my wordpress site again from steemit but it seems like there is only a plugin for wordpress to steemit.

Interesting article and project @futurethinker
