Venkatesh Rao describes three kinds of corporate neo-urbanism, represented by Google, Meetup and Zappos respectively:
You could attempt to create the right environment within a large campus, located sufficiently far away from the main urban hub so that it is relatively cheap (Google), you could suck it up and compete for the hipster talent that is willing to pay the costs of Big City life and limit your growth (Meetup), or you could attempt to swallow a likely cheaper location whole, and catalyze the emergence of the neo-urban scene you need for your workforce (Zappos).
