The amount of work notwithstanding, all of the questions I posed to Karen were based on the reality facing GNOME as she takes the job. "Happy smiley faces" are not really the objective - asking legitimate questions is. As a long-time user of GNOME, I don't see the current release as a marked improvement. As an observer of the industry, I only see one company that seems pleased with GNOME Shell -- and that's a company that doesn't express any interest in pursuing desktop Linux. The company / project that has the largest share of the Linux desktop has essentially rejected GNOME Shell and seems to be moving towards Qt.
In short - The questions were legitimate, and you can be pretty sure other reporters will ask the same things if they interview Karen.
