If I'm attacking anything, it's her record as a leader. We can agree to disagree on that, but I see nothing personal in my comment.
Secondly, the heart of my comment is how some people are raised up to insane heights on mediocre achievements. Even if she was a great "gatekeeper" as you say, there's really nothing in that skill that sounds particularly impressive and certainly not worth the obscene amounts of money and praised heaped upon her up until her public fall from grace.
And while I'm at it I suppose I should chime in on Instant - always seemed like a waste of resources to me. What is so hard about hitting Enter? Personally it always annoyed me. Obviously many people will disagree with me but when I found out that one of the most annoying changes to google search had been pushed hard by Mayer I couldn't help but comment.
