As an business owner, I've used this site for recruiting. I got some excellent applicants, and have made a couple of hires. But they're expensive. So, a little over a year ago, I decided to run a side-by-side comparison and advertised the same opening for a $45K/yr salaried business position on careerbuilder.com ($400 cost of ad) and on craigslist ($25 cost of ad). The numbers and quality of applicants were similar. Since then I have done my advertising on craigslist with excellent results.
