Here's my observations on some content farms that I visit from time to time:
Read what Brinked said in this [webmasterworld.com...]
They (content farms, those that eventually escaped Panda) have done all what they can to make their content farm sites look interactive & worth reading.
Meaning, they improved the user experience by adding videos, related content, images, good nav boxes, etc etc etc.
They also deleted hundreds of thousands of zero traffic pages + structured/categorized optimally their best content.
I actually compete two or three about.com sub domains, and I can tell you that they are making a good job having several writers with top SEOs making every page optimized to its neck.
Google algorithm has a hard time recognize whether this content is 100% good or not, because visitors continue to dig reading.
Sometimes it is 'good enough' and sometimes not.
