We love your service and filled two positions that we were looking to fill. I get approached by staffing companies all the time and I see no reason to use them when I can just post the job opening on Stack Overflow and get amazing people.

The type of developers that regularly use Stack Overflow are the type of employees we want to hire. That is, by using Careers 2.0, we know we are targeting people from a community of talented, like-minded individuals. Additionally, the proactive customer service from Stack Overflow has been impressive. Our account executive was insanely good.
