It seems the dust is not settled yet...I have seen many fluctuations for some terms I checked throughout the day today!
Also my client is seeing different results from a different city. One thing we noticed is a new kind of geo targetting, which targets keywords in the URL path! I had not seen this before, but it may be totally unrelated to Penguin...From Burbank, CA, I am seeing my client's internal pages that has the words "burbank" or "los angeles" in the URL rank here locally, but my client is seeing totally different pages in San Diego rank around the same positions!
