Here’s a statement from Karen Redetzki, MSN Product Manager:
“In order to increase relevancy, MSN Search is testing solutions on MSN Search to a small percentage of consumers in various markets worldwide. Tests serve as no indication as to the direction MSN will eventually take in the future but rather are research to determine the most useful consumer experience on MSN Search. Tests or changes in one country do not necessarily indicate what may or may not be tested or changed in the US or other markets. We determine the needs of customers in individual markets and make the best decision for that market based on both consumer and advertiser wants & needs.”
