My reaction is very positive. It has taken me several hours to read this, fully digest the ideas, and understand more from talking to others. I sat down to write a comment, but it became a separate post about the roadmap (I won't spam, but you can click on my blog if you're interested). I think the Communities thing is brilliant and I am glad about the gamification, using the Steemit account to fund development and promotion, and several other great things in here. Terrific job, guys.
