Suprisingly enough, this really is the release announcement. This is their marketing department.

Scott Hanselman ... Microsoft employee.

It's Microsoft's new marketing strategy - they try to promote 'organic growth and acceptance' of new products through social media and viral advertising. I don't believe it works very well - it always comes across as a bit false and pollutes the real comment environment, giving viewers the strange feeling that something is wrong. It also creates a lot of antagonism when paid employees actually argue with detractors, etc.
