Perl certification is brought up all the time. The responses are always the same, people say "this has been brought up before" and proceed to ignore the question. It then gets to the point where it becomes frowned upon to discuss, even though very few good points were ever made.

Fortunately, there is a very small minority out there that doesn't take this approach. Maybe they're not aware of the general consensus, or maybe they just don't care. They just go ahead and do it. While others sit around regurgitating the same answers they were given when they asked the question, these people are giving it a shot.

So I say go for it. Start certifying people yourself. Offer some free training and certification to get started. Become an authority on the subject. At worst, it will cost you a bit of time and you'll end up that much smarter. Pay no attention to these lemmings. Who needs anyone's approval?
