The company actually doesn't care about the certification, at least not for developers, tech writers, and QA analysts. They care about the concepts and terminology getting disseminated to everyone involved. The certification test is free with the class, so one may as well take it.

I'm not aware of any meaningful certification for Perl. We do have trainers come in for Perl, though. I'm sure merlyn would approve of brian_d_foy being in the building for example. He is right now as a matter of fact.

As far as I know we have a few infrastructure things that run on JVMs but our products and our infrastructure neither one involve any in-house Java. I've read through some Clojure to get a better idea of what some third-party tools are doing but we don't write it here. We do some Ruby on my team and some C lurks in some corners in various parts of the company. I'd actually love to get a good Ruby trainer in here for a few days.
