Andreas is not a great choice. His people skills are terrible. They are so bad that he no longer writes his own emails to employees. They have to go through a PA to make sure they have a human element.
The @RealAndreasGal twitter account that was recently deleted was so amusing because the things that it said were exactly on point. Same with the 'ShitGalSays' Tumblr account which is still around: http://shitgalsays.com/
Andreas is strongly pro-whatever partners want in Firefox OS. Expect DRM and other forms of lockdown to start appearing under his rule. He has no interest in the Mozilla mission.
