The string of large companies adopting WordPress continues to grow.  From a post by Matthew Mullenweg, one of the original WordPress developers:

WordPress is also trusted to run sites for some of the largest and most security-conscious organizations in the world, including Facebook, SAP, Glenn Greenwald’s The Intercept, eBay, McAfee, Sophos, GNOME, Mozilla, MIT, Reuters, CNN, Google Ventures, NASA, and literally hundreds more.

There’s also, oh, say, small local enterprises like the University of Washington, Washington State University, and Gonzaga University.

WordPress is just a great, safe, effective, and most importantly credible solution for the most important place to have a presence on the internet: your place!
