What to expect when you're an executive who's expectingWhy make such a fuss over who's disclosing their pregnancies? I worked at Wired Ventures, then the publisher of Wired magazine, in 1996 and 1997, in the midst of the agony of its failed IPO attempt. One controversy at the time was the disclosure that cofounder Jane Metcalfe, the magazine's publisher, was pregnant and planned to take maternity leave shortly after the planned IPO. For the record, no one I know believes that Metcalfe's pregnancy had anything to do with Wired's troubles. But for a top executive to take a leave is always a strain on a young, growing company, and is a fact best disclosed, as Wired Ventures did. Hence my surprise that Mena Trott waited until now to talk about her news. Caterina Fake, the cofounder of Flickr and an executive at Yahoo, has, by contrast, written publicly and often about her pregnancy. More on the status of Fake's pregnancy, and the rest of the couples mentioned in our poll, shortly.
