These aren't mutually exclusive goals. We have people dedicated to growing and maintaining the community (on Stack Overflow, as well as the other sites in the Stack Exchange network), people who work on large feature areas (e.g. Documentation), yet more people who are focused on the Jobs and hiring/recruiting experience for developers, etc.
I'm more curious to know how these affect the profits of StackOverflow and what gets more bang for the buck or if random ideas are being tried out seeing which one sticks.
