What I mentioned here [webmasterworld.com...] was on Friday the 7th. It wasn't until the afternoon hours that we saw 50-100% spikes in certain keyword traffic. Things don't feel back to normal yet, as someone mentioned it usually takes a week for algo updates to finalize and we're waiting a few more days to breath again.
In all, there hasn't been a overall shift in the daily traffic %; we lost some long tail searches in favor of shorter terms with higher traffic.
