IMO it probably had little to do with the meta change but instead ANY change. Right now content changes are a killer. Try changing one of your lesser pages and watch it drop like a rock. Reaffirms the idea that "new" is bad right now.

My take on it is they revalued all our sites. Old content got old rankings. New content is ranked based on the new site valuation.
