On the Web no subject is sacrosanct. No one, from icon to unknown, is off-limits.

Maybe "having enough" has a second meaning beyond the basic economic security a family needs. Maybe it means accepting that a rich full life with a job and family will be rewarding, but it certainly won't be perfect. As many of us who have combined kids and careers know all too well, some days it's really pretty messy. And that's OK.

Susan Wojcicki at Google makes a point to leave the office at 6 P.M. After 9 P.M. she gets back online to handle any pressing work issues that need her attention. She told us she hopes that sends a message to all parents that it's OK to spend time away from the office. All the women we spoke to on the show use technology in a similar way. They are very clear that they don't need to be chained to a desk. They can take time out of their work day to be with their families.

The new buzz word in Silicon Valley is "integration". Work-life "balance" is very 2.0. All these women share ways in which they integrate their family life and work. Facebook's head of Global Solutions, Carolyn Everson, for example, takes her children along on her business trips once a quarter. They meet her clients, visit new places and get a better understanding of what mom does when she isn't at home with them.

Wrestling with work-life balance is a luxury when working to support a family is a necessity rather than a choice. I think that focus is only partially a result of these tough economic times. I think it also reflects a bit of "having it all fatigue": women are worn out from feeling the pressure to excel at work, and be the perfect mom at home.

Social activism has gone mainstream. A new generation of philanthropic leaders such as Bill and Melinda Gates, and Bono are providing inspiration, guidance, and billions of dollars through their global foundations.

I want to shine a spotlight on a new generation of women, who are creating, funding and managing some of the hottest companies in tech today. But I wanted to do more than share their professional stories. I wanted to share their personal journeys, too.
