Ask HN: Anyone taking the C++ Grandmaster Certification?

Is anyone taking the C++ Grandmaster Certification (http://www.cppgm.org/)?

When it began, there was a discussion were some people pointed that this would be a herculean task, others suspected that this was a hoax. I'm asking for feedback, positive or negative, from people who might be doing this, or started and then dropped it.
