Appears there are two types of people,

The 37Signal employees: * Like their field and want to be 'hands-on' * Don't mind staying in the same company for 10X years.

The supposed norm: * Prefer to advance to other positions vertically * Like moving between companies (for challenge/change).

Makes me wonder what is the difference between the two types of personalities and how those affect the organization.

For example, is there more or less innovation in 37Signals ? Are people more ready to step up and fix/report problems outside their immediate responsibilities ?
