I've recently been seeing, beginning roughly Thursday (April 14), that, for a given query, Google appears to be shifting the entry page it returns for a site to pages that it's deciding are more useful. It could have been happening sooner.

I've been seeing the same thing--even for WebmasterWorld. I used to type in webmaster and get the home page for WW in the top ten SERPs. But lately it's been offering this page:

Webmaster General:
Got questions or comments regarding your site not covered in another board?. WebmasterWorld Webmaster General.
