Went to mail.yahoo.com to check my mail there (for the first time in months.) The landing page had nothing to do with mail and everything to do with piles of crap that Yahoo wants me to look at. Congratulations Marissa, that's the last time I'll even bother looking when you say "Look! We've changed." Next.
Why did you pin this on Marissa instead of Yahoo? She signed her name to it, but if Bill Gates or Steve Jobs did that, you would have said Microsoft or Apple. Granted, her name has a better brand than Yahoo still, but she's working on that. What you said sounded sexist, and I'm not even a feminist or a female.
Perhaps he's pinning the blame on Mayer because the announcement was written and signed by her! It's the role of the CEO to represent his or her company in this manner and serve as the lightning rod for any feedback. The fact that Mayer is a woman is completely irrelevant. Both Jobs and Gates (and many other male and female CEO's) took on that role, and there is absolutely no shortage of rants and raves over the years directly addressed at them.
In fact, I would say that you are the one being sexist, since you are apparently accusing jpdoctor of sexism based solely on the gender of Yahoo's CEO.
