Whenever I sign out of Yahoo! Mail I am directed to their homepage, and there's always a lead story like, "Basketball Player's Amazing Shot", or "Top 10 Best Cities to Live In", and more recently, "Jobs with the Highest Starting Salaries!"
They tend to run a version of that last line quite often. However, I never see them running "Careers that Make People the Happiest!" Always the money story.
I have to assume they run these stories based on how many hits similar stories receive. Leaves me wondering if Yahoo!'s European homepages are running the same stories, or if they don't seem to care as much about the "money" articles, and are more concerned with the "happy" articles.
