In amongst the comments in the Hypercritical Analysis of WordPress themes post over on WPCandy came an interesting stat from Brian Gardner of StudioPress.
Rough numbers indicate that a 1/4 million sites are running Genesis. I’d say that’s a stable environment to build for.
That’s a huge number in my opinion – especially as the framework has not been around as long as some of it’s competitors. We’ve made no secret of our love for the Genesis framework and it would seem that we’re not alone by those numbers 🙂
