I don't know who built the site, but it is a good social publishing showcase. They actively encourage all R.E.M. fans to share and catalog the content they've created. They show the most recent tweets, Flickr photos, YouTube mashups, concert footage, etc. All very cool!
Sportswear manufacturer Nike is using Drupal for their Beijing Olympics website. What is remarkable is that the content on the site is being translated to at least 13 languages (see language drop-down on screenshot). That is a testament to Drupal 6's improved internationalization features, and further proof that I'm not crazy. ;-)
If anyone is working on internationalization improvements for Drupal 7, let me know. I'm accepting patches ...
MotoGP is the world’s premier motorcycling championship, with a season of 18 Grands Prix in 14 countries bringing together the world’s top motorcycle manufacturers such as Honda, Yamaha, Suzuki, Ducati, Kawasaki, Aprilia and KTM - plus an elite crop of riders from every corner of the globe. Their website just relaunched on Drupal: see http://www.motogp.com. Rumor has it that on racing days, they serve up to 2 million pages a day. Yowza!
