Getting certified in whatever will help. Learning is always "a good thing". Certification is an easy measure to demonstrate knowledge in something.
Having certification makes you (as an individual) stand out from the pack.
My IT Services company of over 100,000 encourages certification. It'll help us too stand out from the pack.
Even if you don't have real world experience, certification proves you have the interest and capability of doing something in that area. If an employer doesn't know you from Adam, it will help them feel more confident in your skills and helps open the door to getting an interview.
For someone in the industry already, even though these certifications may be broad-based, and have may have little to do with what you specifically do on a daily basis, it helps broaden your view of your area of expertise and may expose you to some concepts you weren't aware of (as a result of preparation and research).
It is admittedly sometimes a pain in the butt to find time to study for these things and may not really be that important to a person of higher knowledge or one with years of work experience.
But, then again, one might say, for such a higher level of knowledge person, a certification should be a trivial thing to accomplish.
....at the minimum, read, study, learn continuously...
