I find it hard to believe that people have over 10,000 pages of quality content.
We need to put things in PANDA perspective. All domains are impacted including YouTube... YouTube has tons of low quality videos that Google does not want to rise to the top... but YouTube's value to the web isn't the millions or billions of videos but the 10K or 20K really exceptional ones and those are generally determined by natural links pointing to them.
A few pages of gems can easily support 10,000 pages of crap. It's the gems that drives your ranks and thus traffic. People got stuck on longtail because you can rank crap easily for 1 or 2 clicks but Google reset that to stop the crap from appearing just because you can manipulate with a few tricks.
