Yahoo! has a lot to learn. Soon. Their ads are absolutely gaudy, they lean left, and now they've made the 'Personals' link on their home page pink, like it's been visited -- "No, honey, I really haven't been there. Really." So, their not recognizing today's Mozilla/FF evolution isn't surprising.
Haven't seen that part of Yahoo .. that's very tawdry. I do like them better than Google .. just for the front page for Yellow Pages, People Search .. wish Google would make their front page more content-rich and easy to use like Yahoo.
