What is the OP's point? That people don't pay attention to the gender of the writer? If someone did a dedicated study about the last 6 months of top Hacker News and top r/programming articles what percentage do we think would be male authors? I would set the over-under at 95%. (Please don't point out that those audiences are sexist because the OP just showed that the readers don't pay attention to the gender of authors.)

For the record I think there is sexism in tech but it mostly starts in jr high and high school - at least in the US.
