I found the secret to Panda 1.0-2.1
To late to edit: on 2/24 a certain site on my niche ZOOMED and it even made it in the Panda up/down list because they had amazing and very unique and useful That's one site I didn't mind moving up :) even though the pages are perfectly fine without that, although a bit thin.
Now, if we remember many of us also had some 'good' pages still ranking, remember? And then we got a few more here and there, here today, gone tomorrow. Where are they now ;)?
In April and May his site crashed by 70% all of the sudden and is 40% down year to year...some 2x% down compared to pre-Panda. (The numbers are rounded up, my head is hurting and Compete /Quantcast estimate them anyway...but generally speaking)
So it is my belief that Google gave up rating content and pages and added something to rely mostly on site stats. So a 'good site' even if it has pages that relatively suck they will more than outrank one with very good content. User metrics cannot be better than the sites that crashed in April and May, if you calculate them per page.
Moral of the story: it does not look good at all, these "quality improvements" will most likely kill for good many small but very useful sites. And they will probably move to other niches little by little. So instead of having great pages, you have to become a brand while you are broke and then maybe...just maybe.
