These types of articles keep showing up... and sometimes, maybe it really is down to a difference between men and women, whether a socialized difference or something more innate.   I've been working in the tech sector for the last 15 or so years, and while there are women working with technology - as programmers, QA, and yes leads and managers - the men do outnumber them.  I know very few women, including young women starting out in the working world, who are as interested in technology as their male counterparts.   It's just the way it is.  I think there are far fewer barriers to women in the tech field than ever before, but I'm not sure the 'gender gap' will close that easily if the volume of interest isn't there.
