Hello cryonerve, and welcome to the forums.

I think most of these changes are changes and enhancements to the ranking algorithm - they go well beyond bug fixes. And some of it seems to be actual bug creation ;)

We maintain a regular thread every month where members discuss the changes they see in the SERPs. The one for the current month is here: June 2008 Google SERP Changes [webmasterworld.com]. If you track these threads over time, you'll see that our members pick up on a lot of the tweaks.

Google is not about to list for us how they are adjusting the algorithm day by day and week by week. But our community has noticed a lot.

Here's just a few areas recently discussed: some major changes to how Google handles repeated queries from the same user, "forced" ranking positions for certain types of search results, efforts to create diversity when a query is too ambiguous, changes to geo-located results, changes to the way link juice is calculated, major changes in linguistic handling (including mixed case queries), shifts in the way quoted search terms are handled, and on and on.

As good as Google Search is today, I think most members here feel they've got a lot more to do - and Google definitely agrees with that.
