As posted by Ed the day before yesterday (Shorter path to Notes/Domino 8.5 certification) the certification path for Notes/Domino 8.5 is being simplified from September 2011. I used to have a somewhat strained perception of certification but after my own Lotus Connections certification I'm a firm believer. Certification makes you take the product seriously but I haven't always agreed with the required number of tests. This change makes me a happy camper! :-)
I have also within the last two months seen the level of expertise acquired by co-workers rise as they study for and take the exams. It is not as hard as it might seem.
Come on - what are you waiting for?! Go sign up for certification.
