It is imperative more women start businesses especially in technology. Women see things differently, bring fresh perspective and can be more collaborative and less proprietary. I know sweeping generalizations are dangerous, but go to any tech startup weekend and it may be as much as 80% male. In my 30 year business career I've noticed an important truth - diversity trumps all else.
Diverse teams perform better (read Wisdom of Crowds for why). Teams rich in diversity perspectives, background and gender perform consistently at a higher level. Hope this new book encourages more women entrepreneurs especially in tech.
