The quote from the article, “my work life sort of is my personal life.” is the common attitude put forth by the sort of employees that a company like Zynga attracts. Young, without family or interests outside of work.

A company with a focus on long term employees that will stay and focus on the underlying structure that permits the business to exist will be more interested in hiring and retaining employees with interests that encapsulate more than simply staying late into the evening to "crush some code."
