Panda softening? Any thoughts on the detail?

[Gavin.Atkinson]

At PubCon 2013 I notice Matt Cutts mentioned Panda softening and I wonder if anyone who was there has any greater insight into what they are thinking? Is Google finally responding to the overwhelming number of webmaster complaints about Panda? What sort of issues might they be responding to?

"We are looking at Panda and seeing if we can find some additional signals, and we think we've got some to help refine things for sites that are kind of in the border zone, the gray area a little bit, And so if we can soften the affect a little bit, for those sites, that we believe have got some additional signals of quality, that will help sites that were previously affected - to some degree."

All I am seeing on the discussion forums so far is more blah blah blah...
