very cool info. following the growth of steem is more than trivial. we might be watching a major shift in how people interact online unfold in front of our eyes. the question about gender statistics might have to do with two things that over time will balance. 1. is steemit is new and has an element of feeling risky which in general females are more risk adverse 2. the topic of cryptocurrency is a major push for steem and that tends to be more male dominated (again risk). I suspect this will change as steemit becomes mainstream.
