In a social and transparent world the reader gets very quickly a good impression of Marissa's personality, views and hard facts - being able to better assess "who is Marissa Mayer".
In an individual and global world where it is important to be visible and to stand out of the crowd such a CV can make a real difference.
From my point of view this could be a wonderful HR application form within the recruiting and talent management process. Easy to design, program and to apply for all stakeholder groups.
