I'm not sure how you can hold Meyer directly responsible for the clunky Yahoo email client. This reads as incredibly sexist.

What does Mayer's floundering in her post-Googler-career as Yahoo's CEO have to do with the product failures of Picasa and Finance? Referencing her in this context makes as little sense as referencing Andy Rubin -- another prominent Googler who went on to flounder as CEO.
