GROKLAW: Women in Free Software:

"Another important point is that Free Software development is often done as a hobby, just for fun, and in one's spare time. Where is a woman's spare time? After their working day, most of them still have the second working journey, which is at home, taking care of the home, the children and her husband. If the men can have the privilege of doing Free Software in their spare time, sitting in front of the computer and having some fun coding what they want, women in general don't have this privilege."
