Google tweaks algorithm; content farms and splogs wail and rend their spammy garments

Google this week launched a significant change in search algorithm intended to push down low-quality, SEO'd-out-the-ass content farms in favor of less spammy sites with more useful information. NYT article here, and the original Google announcement is here. Google says the change "noticeably impacts 11.8% of our queries." So far, it's US-only, but will roll out to other countries over time.

Wonder how this will affect popular sites like HuffPo, or other blogs and news sites that repurpose a lot of content from other sources? And reportedly, folks at eHow aren't bothered by the news: they perceive their content to be so high quality as to not be targeted by the shift.
