several sites who've been working hard on Panda issues reported improved rankings on Sunday
Are we looking at a roll out of several days, maybe a week or just this. My hunch is that this is just US/.com and the roll out internationally takes a little longer.
Not sure where @Marketing_Guy 's website is based - but he appears to have been the earliest.
I've not seen any reports, of comebacks after Sunday. It's pretty thin out there - again much more inputs are needed.
