I got a burst of traffic increase but in very early morning. Now looks like Bing and Yahoo are catching up to the 'normal' numbers compared to Google referrals. Yesterday afternoon I got higher than (new) normal Google referrals too.
edit: AlyssaS, it's Panda time, Google has been running them every 4-5 weeks but last 2 no one came back (as far as we know). Either way it's probably too early to see what the change was about, the serps are still moving around.
