The Washington Post has completed a pretty long redesign process with the launch of their new homepage. Journalism.co.uk has an article on it and note that about 70% of The Washington Post content is powered by WordPress.
If I were building a big-world news website, I would want it to look like this one. It is stunning, and an excellent showcase for what WordPress can be a part of, even if not 100% power it; this should be on everyone’s list of awesome sites that use WordPress.
