I think that other women may take different choices - if I didn't want to have kids, I would be all over working on a start up, but as it stands, I wouldn't think about it until I am older.
I think that the article has its plusses and minuses but one thing we should all agree on is that the YC model should be adopted for the needs of many different groups. I won't want to do anything risky until my kids are more independent and I've built a solid nest egg. But my fiancée feels the same way as me! So, I don't see why the article needs to be quite so gender-specific. I would like to see this idea come to fruition, with emphasis placed on attracting more women to the field but maybe geared more towards anyone 35-40+ who has a family and responsibilities but would like to take on a start up project.
