I'm glad to see this.
I can't believe that in the US, paternity/maternity leave is something that is left for 'the market to decide'. I was hoping for Marissa Mayer to lead and set the example for maternity leave... but she took two weeks... I couldn't really believe it, I was pretty disappointed. In my eyes what she did, sent a pretty sad message for women, her employees, and other companies.
I think Mark taking two weeks off, is an example, for everyone. His employees (male, female, etc) and other companies. Hey, maybe even the Government can learn from this.
TD;LR, glad Mark did this. Kudos.
