What is vExpert?
From the vExpert Landing Page: The VMware vExpert Award is given to individuals who have significantly contributed to the community of VMware users over the past year. vExperts are book authors, bloggers, VMUG leaders, tool builders, and other IT professionals who share their knowledge and passion with others. These vExperts have gone above and beyond their day jobs to share their technical expertise and communicate the value of VMware and virtualization to their colleagues and community.
You can notice that it isn’t a new type of certitication but a award (quite similar to Microsoft MPV).
