Thanks a lot for this insightful data !
Although what is strange for me is the differences in "Not active" / "Fully active" categories depending on the source of the account creation. Would be great to have more info on that.
Maybe see for the active users (excepted the ones created by Steemit) the type of activity (vote, post, through which app, etc...) to see retention factors.
