    Hi Nishant, thanks for commenting. Our goals are:

  1. Make sure all the technical information you need is available on TechNet.
  2. Provide KB articles for any late-breaking support issues.
  3. Blog any information we think might be useful. The difference between a blog article and a TechNet article in this context is that blogs can be written directly by engineers working on features, so it's a direct means of communication. Any information that shows up in blogs and KB articles can become a source for a TechNet article if it includes product knowledge beyond pure support knowledge such as details about patches. We love to get suggestions on particular articles that should go in the documentation or gaps in the current documentation. Thanks Guy
