Joost de Valk, writing on the WordPress.org blog:

WordPress now powers over 1/3rd of the top 10 million sites on the web according to W3Techs. Our market share has been growing steadily over the last few years, going from 29.9% just one year ago to 33.4% now. We are, of course, quite proud of these numbers!

Over the years WordPress has become the CMS of choice for more and more people and companies. As various businesses use WordPress, the variety of WordPress sites grows. Large enterprise businesses all the way down to small local businesses: all of them use WordPress to power their site. We love seeing that and we strive to continuously make WordPress better for all of you.

So stoked to see the rise of WordPress.
