I'm also seeing a lot of keyword domains ranking for no other reason I can see. And my own domain name - which does NOT have any keywords for my site - has fallen to #4. Even though people are searching "my domain", clicking me and not bouncing, I'm not what Google is serving on that query.
@tedster, thanks for explaining that Penguin is an algo and not a penalty, because I've found this very confusing and I'm not sure I'm out of the woods yet. I did fill out that Penguin form for one of my queries - after which point I fell three more pages for it and gave up.
What's confusing to me is that the form says
If your site was affected by the "Penguin" webspam algorithm update
and we've been told Penguin is about spam/aggressive SEO. Well, spam has always been defined as actions a webmaster or service engaged in, so a site penalty was the usual response. Is Penguin treating spam as something that just sort of happens, page by page? Or is it trying to work out relative spamminess on various queries, which would explain why one page from my site might fall but others rise - because the one was relatively spammy for that query, but the other were relatively less spammy for their queries, even though they're probably all equally spammy (or not) in terms of on-page SEO, since they were all created by the same webmaster.
Hope I'm making sense there?
