It appears that Yahoo! continues to make tweaks to the new index and algorithm they set into place on July 13/14th. Webmasters are still tracking the changes in the WebmasterWorld thread.

Ya, just a tweak ... not sure for the better, but just having a look now. Most of the issues with the latest update remain. Looks like the internal site issues are still there (wrong page/right site) and externally, force is certainly outweighing meaning/intent. Putting this much emphasis on external links w/o having theming/mapping, authority, and (ideallly) semantic stuff working well is problematic. Issues that arise include: - quality niche sites with good but not huge numbers of links tend to struggle (I see a little more of that with this tweak, I think) - searches with words having multiple meanings can be awfully bad - lots of links with right words can work wonders for a page/site, even if from only vaguely related and unrelated sites.Add to that heavy handed filters that clip out best pages and feature bad choices from good sites, and you've got a real mixed bag. Link sellers gotta be feeling giddy right now.
Some SEOs are loving it, some are hating it. What did you expect?
