Here is the February 2009 webmaster report on Google’s search result changes based on the WebmasterWorld thread. I will summarize what people are noticing in the Google search results, as per the thread.

Google accidently labeled the internet as malwareSome SEOs noticed index counts double in sizeSome are reporting a “glitch” that promotes .edu & .gov as Google BombsLonger tail keywords seem to be ‘rollercoastering’ in the SERPsTedster’s theory is that Google is tweaking the QDF (query deserves freshness) and QDD (query deserves diversity) algorithms.

That is the bulk of what I pulled out from the thread.
