I know, we just covered huge chatter around a Google update last Friday but there is no doubt in my mind, Google is testing algorithms maybe around Panda or Penguin or the doorway algorithm is being released or maybe a whole new beast.

This morning the WebmasterWorld thread started heating up again. Plus I received emails, social media mentions and more around major changes in the Google search results.
