Someone mentioned site-wide effect or did it affect us page-by-page. I noticed some pages fell while others gained. Is that a site-wide effect? Maybe. Maybe I gained in SERPS that were dominated by lower quality content. The Farmer / Panda updates might have pushed them down "more" than I got pushed. So it appears to be on a page-by-page basis, but in reality it really was sitewide.
