Skewz is a website where users can read conservative and liberal stories selected by other users, and then vote on the liberal or conservative bias of the article. Skewz is driven by the wisdom of the participants who can read the latest news, submit new articles, "skew" and comment on existing articles.

Click on the image above, and in the new screen, select a story and vote on its bias by sliding the voting bar to the left for liberal or to the right for conservative. This would be a great site for teaching point of view.
