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.
I think there is evidence on both sides though, right?
Certainly many sites that had a model of "content sprawl" were brutalized by at least one of the Panda iterations. ehow, for instance, took it on the chin when Panda 2 rolled out.
However, in the niches I watch closely, ehow has made a comeback. For example, their four paragraph article - which cites as a reference my 9 paragraph article full of sample images and an inline glossary - ranks above my page.
Heck, the ehow article ranks ABOVE the wikipedia page of the same topic. :[
Also, another site I seem to run into at the top of the SERPs when I am looking for something on google is about.com - which may rival ehow in terms of subject numerity and content dearth, while still shoving ads into every empty space on the page.
Why this is, I have no idea. But I would just kindly suggest that there is something out there that we might be overlooking.
