Tim Mayer from Yahoo! blogged today an entry named Second Weather Report: Yahoo! Launching New Search Index Tonight. The first weather report was named Tim Update because Tim announced it, I wonder what this one will be named... I am pretty sure they rushed this new index out before the WebmasterWorld conference but Google already has the name Bourbon Update.
The weather report reads;
We will be making changes to the index tonight so you should be seeing more of your pages in the index as well as some fluctuations in the rankings of results from previous searches.
