If I recall correctly, wasn't the reason Jeff Atwood (codinghorror) stepped down from active work on StackExchange owing to spending more time with his children? I'd be interested to know his view on this article. Edit: Also, my PhD supervisor went part-time after he became a father. But these are the only two examples I can think of of professional men making a career sacrifice for spending more time as a parent.
