What is an MVP?
The MVP award is a one-year renewable reward given to just under 3,000 customers worldwide who are community leaders for their past year's accomplishments in a specific competency (ex: ASP.NET, C#, VSTS). A non-Microsoft employee is nominated by an employee or other MVP, their contributions to the community are evaluated, and they are voted on by an MVP Lead and PG Lead. Contributions can include answering MSDN Forum questions, writing articles & books, having an active & popular blog, working with the product teams, running a local user group, giving presentations, etc.   A quick intro to what an MVP is can be found on the MVP Website.
