I found out that the author had a lot of free time (otherwise, how can you justify the learning/testing the platforms?). That is incredibly good for himself to learn all of them but seriously, why?
they've always been only money burners, because certifications are tight to specific technologies, that gradually are disappearing with the time (Think to all those MSCE Windows Server 2000, 2003 or old RedHat ones).
I'm happy that they are having this problem, perhaps leading them to reduce their monthly fee instead of increasing it deliberately. It's annoying me that you should hold multiple accounts to watch "exclusives" on specific platforms, making it really expensive, especially for young people.
