"Been busy, how 'bout y'awl?"

Not too busy. Taxes, search engines. You know. :) Supplemental results are results that we can show for some more arcane queries that typically have fewer results. Danny Sullivan had a good write-up about them a little while ago: http://searchenginewatch.com/searchday/article.php/3071371
It is a different index, so some of the results can be a little older, but some of the supplemental results are pretty up-to-date too.
