My impression is that the biggest impact MM had since becoming CEO of Yahoo! is the change in perception at the level of Wall Street, journalists, and analysts. "She must know what to do. She's been so high in Google ranks" By no means I'm implying that MM doesn't have a plan and some signs can be seen here and there from a customer perspective: better iOS apps, a budget for Flickr, more users through the acquisition of Tumblr, etc. But at the end of the day, what matters for Yahoo! the company is this:

> In eight of the nine quarters that Yahoo has completed since her appointment, its display-advertising revenue has seen a year-over-year decrease.
