Not the way I read this at all - this update was about dupe content - not low quality original content.
"Earlier this week Google launched an algorithmic change that will tend to rank scraper sites or sites with less original content lower. The net effect is that searchers are more likely to see the sites that wrote the original content. An example would be that stackoverflow.com will tend to rank higher than sites that just reuse stackoverflow.com's content.
That is not about so called content farms like About.com. That statement is about dupe content.
Show me where Matt says anything about content farms?
I am willing to concede that there may be a wink-and-a-nod going on here where Matt doesn't want to use the 'farm' word because of legal fallout, but I didn't read this as pointing at content farms yet. I think we need to get this story right. This is very important to alot of people.
