Yesterday’s Slashdot morsel entitled “MSN Search Engine Favors IIS” doesn’t really come as a surprise. Ivor Hewitt found that search results on the new MSN Search favour results from sites running on Microsoft’s IIS server.

His research shows as much as a 10% bias in results, using thousands of queries made up of random words, though he admits the bias may be down to MSN developers’ familiarity with coding applications that talk to IIS servers.
