Customers of what, exactly? I've not heard of anyone using Yahoo, except those that are holding on to Yahoo email addresses because they don't know it makes them look old and technically illiterate.
I use quite a few of their services, some for legacy reasons. I use Flickr, admin a few mailing lists on Yahoo Groups, and am just in the process of convincing my muscle memory to move over from finance.yahoo.com to finance.google.com.
My guess is that Google Finance and other copycat sites (albeit better sites in some cases) that they have built are not good investments. If it isn't core to them I don't expect them to keep working on them.
He already told you, they are good with the goddamn customers. They have people skills, they are good at dealing with people. Can't you understand that? What the hell is wrong with you?
