The following is a comment that was posted in response to this article.
Be it typing, driving, smoking or whatever, my opinion is that men tend to do it first, when it is a pioneering activity. When the activity becomes well known, women will also start to do it in large numbers. If it is an activity that is eventually given up, men will give it up first (as can clearly be seen with smoking, and is also true of television - a high proportion of which, being soap or reality TV of some sort, is clearly now designed for a female audience). Thus, if a study were to be done, I strongly suspect that women in the workplace will be most prolific in areas where the methods are known, and only change slowly - like management, law, medicine and retail banking, for example.
