Big news! The world's most visited art museum in the world is now using Drupal for its website: http://louvre.fr. Très cool!

Drupal continues to rack up successes among large developer communities, with x.commerce joining Twitter, which made the move last month. X.commerce is a new division of PayPal that serves as an open, central meeting place for over 700,000 developers for eBay, PayPal, Magento, and other eBay properties.
If you watch the stream of new modules going through drupal.org, it's easy to miss those with special meaning. So you might not have noticed the appearance of Content API, an add-on to the Services module. The module was born of efforts by the U.S. Federal Communications Commission (FCC) to make 350,000 of its documents more available to the public, as part of a site that will enter public beta in a few weeks, My.FCC.gov.
Starting today, Twitter's developer community lives and breathes on Drupal! Check it out at http://dev.twitter.com.
Did you know that in the United States, you can only get married in 5 states if you're gay? I think that's insane.
That's why I'm proud to say that Friendfactor is a Drupal site. Friendfactor is an organization that makes it easier for friends to help their LGBT friends achieve full legal freedoms and equality.
A lot of the recent “scores" I've listed on this site have been from serious institutions: ING, Investor.gov, The U.S. Small Business Administration, and The World Economic Forum.

The Basque Parliament has recently replaced a portion of its older site with a new Drupal site that can be seen at http://www.parlamentovasco.euskolegebiltzarra.org.
This continues the trend of various government bodies around the world using Open Source software -- and especially Drupal to power their official websites.
IKEA is everywhere. With over 300 megastores in dozens of countries, it's one of the world's most recognizable brands. Chances are you have some IKEA furniture in your home -- I certainly do.
You know when a piece of software is mature when it starts being adopted by financial services organizations. ING Financial Services recently moved a number of sites from Oracle Stellent to Drupal. Among these sites are http://ing.us, the main portal for their US market. The driver behind this migration was to move to a platform that was more dynamic and provided faster time to market.
Investor.gov recently switched to Drupal from WordPress. The site houses a lot of information for investors.
The new investor.gov is a good looking site that also seems to be 508 compliant (for accessibility). The site is easy to use, making it easy for users to get the information they need without being overwhelmed.
All in all, the site is great example of how governments can leverage Drupal to create beautiful and accessible sites. Nice work SEC!
