I see a lot of SERP fluctuations in my niche, but overall this update has been great in my niche. All those EMDs with shady backlinks have disappeared completely. I've also seen some totally irrelevant pages(irrelevant title and content) and some with very little content rank very high for some queries. LOL, EHow seems to have snuck back in for some terms.
