I have to add my 2 cents. Something did happen last week. Up until Panda my sites always went up in traffic for a week during and update then leveled out the week following the update. Post-panda is the opposite - site traffic down for the week then recovers the week after. Last week our traffic was down over the previous weeks but we seem to have recovered on the weekend.
