Sheryl Sandberg and Marissa Meyer have already accomplished more than most. I think the sky is the limit for them professionally. If they can inspire more women to "lean in," as Sandberg so famously describes it - to pursue a career and a family - that would be an incredible accomplishment. If they can, by their example as hands on mothers and high powered executives, show young women that they don't need to leave the workplace when they have children, they will be superheroes.

With a click of the Post Comment button, Netizens can quickly bring down the level of dialogue. Bloggers lob zingers, commenters trade barbs, and bullies target kids in the cyber schoolyard. Mudslinging - a time-honored political tradition - thrives on the Web.

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.

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.

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.

For women of my generation, it was the 'juggling act.' Jobs, marriage, children, homes, and aging parents were the balls we added, tossing them in the air as our lives filled up and praying they wouldn't come crashing down on our heads.
