Matt Mullenweg, writing on his weblog:
Sometimes it goes up and down through the course of a month, but it’s still a pretty fun milestone that we can now say about one in four websites are now powered by the scrappy open source underdog with its roots stretching all the way back to a single person in Corsica, France. We should be comfortably past 25% by the end of the year.
The big opportunity is still the 57% of websites that don’t use any identifiable CMS yet, and that’s where I think there is still a ton of growth for us (and I’m also rooting for all the other open source CMSes).
As someone who’s been using WordPress for nearly a decade, I couldn’t be happier about the growth in market share that Matt and the folks at Automattic have managed to achieve. WordPress might not be as slim and streamlined as it used to be, but I consider it to be the absolute best content management system available.
