Yahoo Search Update - Changes in Algorithm

Yahoo is undergoing a major update in their search engine algorithms. It looks to be bad news for people who's sites are not located in the U.S.

My two older blogs (about eight and six months old) have been getting about 120 page views a day from Yahoo searchers. Until today. Now I'm not getting a single hit. Even though these blogs shows up in the top five for some keywords, I believe this is only for viewers in Canada and does not appear this way to viewers in the States.

Is anyone else experiencing this with the new Yahoo update?
