Late last night, Yahoo! announced a new "Weather Report: Yahoo! Search Index Update." They said;
Welcome to our first weather report of the fall season. We are rolling out an index update tonight. As usual, you'll see some changes in ranking along with shuffling of the pages that are included in the index.
What I find very surprising is the lack of forum discussion on this update. Maybe no one noticed much of a change in rankings or their traffic. There is no discussion of this update at Cre8asite, WebmasterWorld or Search Engine Watch Forums.
The only discussion I found was at DigitalPoint Forums and that is only discussing how Yahoo! wrote a post about it at the Yahoo! Search blog.
I believe I see some changes, which makes me think, why are the forums so hush hush about it? It is like Ask's forums, not to knock on Ask.com or anything. :)
