Maybe this is just what Yahoo needs. Let's see how long it takes before Yahoo deletes this garbage off their own message board. If Yahoo can't keep their own message board clear of simple spam like this, maybe Mayer isn't doing such a great job after all.
Yahoo's "JOB" is to sell ADVERTISING (see the 10-K); those are the customers.
Message board posters, and other target audience members, are not Yahoo's "customers" nor is anybody who watches a TV show, listens to radio or reads a free newspaper are those media companies "customer".
