I learned today from Andy Beal, SEO expert and author of many fantastic articles that Microsoft is now exclusively serving Inktomi results.
I've seen no official word of the change thus far from MSN or Inktomi. If you search for a term, however, MSN Search labels the results as "Web Pages" instead of "Directory Listings." The "directory listings" label indicated the LookSmart results, said Beal.
Until now they delivered LookSmart results as their primary results and Inktomi as secondary. Microsoft announced in October that they would drop LookSmart's directory listings.

Also, thanks to forum member greeneagle for this post that alerted Brittany who alerted me. :)
