Skimming through the Webmaster Central thread that asks for people to submit sites they think got hit for no reason, I noticed this post by Wysz (the Google employee who started the thread).

Our recent update is designed to reduce rankings for low-quality sites, so the key thing for webmasters to do is make sure their sites are the highest quality possible. We looked at a variety of signals to detect low quality sites. Bear in mind that people searching on Google typically don't want to see shallow or poorly written content, content thatís copied from other websites, or information that are just not that useful. In addition, it's important for webmasters to know that low quality content on part of a site can impact a site's ranking as a whole. For this reason, if you believe you've been impacted by this change you should evaluate all the content on your site and do your best to improve the overall quality of the pages on your domain. Removing low quality pages or moving them to a different domain could help your rankings for the higher quality content.
