What it takes to become a female Fortune 500 CEO

As Marissa Mayer stood with David Karp to announce Yahoo's acquisition of Tumblr on Monday, you couldn't help but notice the vast educational divide between the two principals.

Karp dropped out of Bronx High School of Science and went on to create a blogging platform worth $1.1 billion.

Mayer graduated with honors from Stanford, earning a B.S. in Symbolic Systems and a Master's in Computer Science--then went to Google (GOOG) as its MORE

After Sandberg, the big money is on women

Maybe Sheryl Sandberg really is building a new feminist movement.

Following the Facebook (FB) COO's PR extravaganza around her best-seller Lean In, the first mega-mover and shaker to join the conversation about women and work was Warren Buffett. The Berkshire Hathaway (BRKA) chief wrote an enlightening essay in the Fortune 500 issue, did his first-ever interview about women (with me), and joined Twitter to help spread his word globally.

This week, Sallie MORE

A tough boss's secret behind her style

Christine Quinn, the mayoral candidate contending to become the first woman in charge of New York City, isn't shy about displaying her true self to the public. She proved that this week by disclosing that she battled bulimia and alcoholism for 10 years until entering a rehab clinic at age 26.

That revelation is stunning—particularly in light of what Quinn, 46, said on Monday at the Fortune Most Powerful Women dinner about learning MORE

How Warren Buffett learned the meaning of success

Last week's interview with Warren Buffett on Women and Work featured a lot of memorable moments. The legendary investor's first Tweet -- the Tweet heard around the world -- was just one.

The most special moment for me, Buffett's interviewer, came when he answered this question from a University of Nebraska student: How do you define success?

"If people whom you want to have love you love you, you're a success," said MORE

How Warren Buffett scored big on Twitter

How do you collect more than one thousand Twitter followers per minute?

If you're Warren Buffett, all you need to do is send your first Tweet:

Warren is in the house.

Fortune (and I) ushered the world's most famous investor into the digital age on Thursday. During my live video chat with the Berkshire Hathaway CEO, he joined Twitter and then sent a followup Tweet to promote his MORE

Buffett's live chat on women and work today at noon

He was itching to publish an essay that he wrote. I'm happy to tell you that Buffett's first-ever piece of writing on women in the workplace advances this hot and timely topic significantly. His essay appears in the Fortune 500 issue, which lands on newsstands this coming Monday.

How women get to (and stay at) the top

Jacki Kelley, who is the CEO of North America and president of global clients for IPG Mediabrands, is one of 36 women participating in the Fortune-U.S. State Department Global Women Leaders Mentoring Partnership. Launched in 2006, the program pairs rising-star women from developing countries with American execs who participate in Fortune's annual Most Powerful Women Summit.

Media-retail star's advice: Go beyond the obvious

Mindy Grossman was a rising-star retail executive, heading Ralph Lauren's (RL) Polo Jeans business and Nike's (NKE) global apparel, before she switched to TV and transformed HSN. By adding celebrity spark and digital dazzle to the once-dreary home-shopping channel, Grossman built a high-growth media-retail hybrid and multiplied HSN's stock price 10-fold from the dark days of 2008. For her unlikely success, she was honored this week at the Matrix Awards MORE

How to make an old career new again

NBC Universal's Bonnie Hammer has been doing what she does—building cable TV networks—for 26 years, which is long enough to know that at a point, the slog of a career can ease and work can turn energizing again. Hammer, who built SyFy and USA Network and recently moved up to chairman of NBCU's (CMCSA) entire cable entertainment group, talked about this notion of belated reward on Monday, when she accepted a 2013 MORE
