On Google support forums another reportedly came back but he posted on Google forums since day one so maybe they looked at his site manually. He was 30% down on Panda and now is back, more or less.
Maybe we haven't come back because we listened to Google post-Panda and deleted pages and then they changed their minds? Sad, very sad. No one has a clue.
Check this advice Matt Cutts gave last year and compare to why we think Panda smashed our sites: [youtube.com...]
"I believe if you were to talk to our crawl and index team, they would normally say "look, let us crawl all the content, we'll figure out what parts of the site are dupe (so which sub-tree are dupes) and we'll combine that together. ...I would really try to let Google crawl the pages & see if we can figure out the dupes on our own.
