A forum member pointed out that the Yahoo Ambassador Program signup page is no longer accepting new members. I'm not able to find any news on this story at press time, but I do have a screenshot of the page:
The question remains: is Yahoo dropping Search Marketing altogether? Forum members say they can still log in and see their reports, but that makes sense for the time being. Maybe, instead, they are dissolving the program and focusing more on Google ads. One doesn't know until someone at Yahoo tells us what's going on.
With that said, what's up, Yahoo? :)
