Also note how responsive he is on Twitter (MG Siegler just tweeted him a question and got back an answer instantly). Somehow, we are in this weird world where MSFT is talking to everyone through a human face and Google has disappeared behind PR statements. That's quite a change.
It depends on which aspect of MSFT and Google you are enquiring about. In this instance MSFT is very responsive but ask about something where it doesn't benefit them to be responsive and you will likely get a cold shoulder. Just like how Google has been very responsive and personal with Google+ but to other requests there is crickets.
There's a fine line to be walked between "caked in corporate-speak" and "tries to be your best buddy", I think MSFT is doing well walking it.
