Joel Spolsky: CEO of Stack Overflow
As a founding member of several successful companies (Fog Creek, Trello) in the software development space, you could say that Joel Spolsky knows a bit about developers. On his popular online forum, Stack Overflow, developers ask more than 8,000 questions a day to a community of roughly 40 million developers who visit the site every month. Joel talks about software developers with a reverence normally reserved for philosophers: "Every day, developers get a chance to make a decision that's going to impact the world," he says. But with that power comes great responsibility, and managers have an important role to play in helping developers consider unintended consequences and use their power for good.
