Linux Certifications and the Job Market

According to this article, getting a Linux certification is not as important is having real world experience. I'd have to say that I not only agree with this, but think it's the way things should be. Passing a test, even a fairly difficult one like the RHCE, is not a substitute for experience. I do think that given two job candidates that are very closely matched, having that extra cert or two could be the difference though. What have others found to be the case?
