I am, myself, a Yahoo Ambassador and enjoy the opportunity to make a little bit of income every time I set up a client so this is somewhat troubling. Why close down the program unless there is a big curtain drawing in the near future?
Here is an anonymous tip we got from a Search Engine Land reader:
Yahoo! is eliminating the Ambassador cert. for all the small businesses and limiting it too bigger agencies and resellers. So they are just pushing out the little players, pretty much trying to make it more prestigious like the Google Reseller Program. You will have to go through Biz Dev people to get an Ambassador Cert.
