Nice, superb analysis and data analytics. Some great data to analyze. Regarding the development of Steemit and SMT. Watch this starting at 4:18:56

on Steemfest 2 last week I think? was watching the livestreams. There was a developer panel of Steemit and you will know the latest developments they are making. Hope this helps the questions on your conclusions. They also announced a mobile app wallet they are gonna release. I recommend you to watch lots of exciting things they are working on :)
