I deal with Yahoo and Google everyday (part of my job) and Yahoo employees are incompetents, IMHO. They should fire their entire search marketing staff and start from scratch. They have glitches in their systems that have gone uncorrected for months. I imagine many advertisers have gotten tired of trying to negotiate the problems Yahoo creates.
I'm getting tired of being bombarded with singles ads when accessing my mail. It's bad enough that they have a "married and looking" option in the profile, but I marked "married and not looking" and still get the ads.
