Maybe its google trying out a new algo which (fingers crossed) they will roll back next week. I seen similar things in the past.
Impact seems mostly localized to my home page. Only things I could do better with my home page are that it's a little fat/slow (rich content) and the title is truncated by Google (despite being only 65 chars). They are the only things I can think of which could cause google to mark me down...
@ausplay - you don't run a WP site do you? With Yoast's SEO plugin? That recently had a big update. Perhaps something there?! ...its the only thing I have changed.
