MSN: UK MSN portal provides glimpse of MSN to come.
According to several sources within MSN, in the near future we will see a change in the layout of MSN search results. The "right rail," as they often call it, will display sponsored results a la Google, and the featured listings (which may be re-named) will be displayed in the main search results area, along with LookSmart and/or Inktomi results.
I think this is only the beginning of the changes we will see at MSN. Time will tell how the results will change based on the altered placement. Watch your log files and reports for changes in MSN based Overture traffic, up or down.
