What this confirms is that Panda is, at least in part, about putting different websites in a box, and demanding they fit in that box, and if they don't, then it penalizes them.
For example... if you run a site called "Blue Widgets" then Google will expect you to write about things related to widgets. If you throw in an article on food now and then, then you may get Pandalized.
This seems strange.
I realize that writing BS on a billion topics is something a lot of content farms do, but writing about different types of topics that may be a little off the beaten path is ALSO something really, really interesting blogs and legit sites do.
This isn't a realistic view of the web at all that Panda is pushing, if that's what it's doing.
