Yeah, I actually read that piece when it was first written, but only glanced at it again when I posted the above comment, as it was already after 2 AM...

As for your final point, the way Steemit works actually means that isn't true, because on Steemit, your SP is your power, and if the only women on Steemit were the top 100 SP-holders, then the platform would be decided by women, even though in absolute numbers their percentage would be tiny.
The top 40 users on the platform hold over 90% of the power on the platform...

But yes, such an environment does not lend itself to more women coming, which in turn doesn't lend itself to more women coming. Though I can say that of all the big internet communities I've been on, Steemit has a much higher representation of women, even if not in the higher echelons. Though it could be just the circles on Steemit I'm hanging around in.
