In the last year or so, I have noticed a big uptick in old handles that were inactive for a long time now participating and self identifying as female. I have long seen evidence that a lot of women here actively downplay or hide their gender. Historical surveys have suggested that 2 to 3 percent of the membership was female, but I believe that figure to be low because of self reported behavior of women hiding their gender. But women appear to be coming out of the woodwork these days.
I hit the leaderboard in October under a different handle. I appear to be the first openly female member of the leaderboard.
I feel there has been a lot of positive change in the last few years.
