Creating a successful two-sided market (with both employers and job-seekers) takes a fairly large site to make it work. Our main site is Stack Overflow (for developers) which has our largest audience by far, so that is where our current careers-related products are focused. There has been some interest in perhaps expanding the listings to include more of our IT-related sites, but I don't know if or when that might happen. But if there is ever a time when we can expand out even further to our smaller sites, it would likely have to be part of a more comprehensive development effort. I'm not privy a timeline where that might be considered, but it is not part of our immediate plans at this time.
