If you visit MSN.com today, you may notice a new look and feel for the site. The beta design is now the new official look for MSN. Like it or not, this is the new look for now.
Greg Sterling reports that about 50% of the Bing search queries are driven from the MSN portal. So this new design may or may not have an impact on that. 50% is major and clearly Microsoft is aware of that.
