Wednesday night, Thursday morning, forum threads starting popping up about a Google "data refresh" taking place. A data refresh is like a small Google update, and many webmasters have noticed a change in the search results at Google. Google has not yet confirmed that there has been an update, nor has there been a ton of discussion on the topic, as of yet. That is why I believe this is a "data refresh" and not a full fledge algorithmic change. Part of the data refresh seems to have put many pages into the supplemental index, an index that no webmaster wants to have their active pages included in. With any update, there are those who feel the index/results has improved and there are those who feel the index/results have suffered. I have more specific details at the Search Engine Roundtable, for those that are interested.
