I've said this several times before, the web is bigger than Google. And with as many new websites coming on line every DAY, it just keeps getting bigger. Panda was a quality change... nuked many sites that are programmatically generated (spun) for the Adsense income, pushing out thousands, to hundreds of thousand pages (some into the millions). QUALITY has become the current mantra... and that actually turns out to be "just as many pages as necessary to cover the subject/topic and no more". As Panda interates through the webmaster community... those of us with the ability to generate thousands of pages the warning is out: "don't do that".
Add to that the number of pages in different languages, DOING THE SAME THING, and it becomes immense.
What to do? If one is a retailer with thousands (or hundreds of thousands) of products, you have that necessity to have those pages.
How many is too many? We don't know. But, those chasing the algo have been forced to look at how they are doing things and have discovered, they CAN consolidate, refine, combine, publish the same info in far FEWER pages and seen some SE "love" return. But no one, to my knowledge, has ever regained 100%+ of their prior Panda levels.
Panda is a wake up. That said, Bing takes a slightly different approach... they don't bother with really low quality sites (humans are involved), just a different approach to the same problem all SEs are facing these days: the EXPLOSION of content, good or not so good, which tasks their ability to provide reasonable results.
