in reply to What is your opinion in Perl Certified Professional?
Why don't we conduct exams for perl.
Because, IMHO, certification rarely benefits the developer. Instead it benefits the certification organisations, trainers and (to a lesser extent) employers.
This topic has come up a lot in the past as a supersearch will show.
I'd also encourage those for and against certification to make their voice heard on the Perl Certification Wiki, especially on VotingBooth, WarStories and EmployerStories.
