Matt Mullenweg, co-founder of WordPress, was recently interviewed on WP Tavern. He had some important things to say about the Customizer at 1:05:00 into the interview (transcript below):
At WordCamp US you said that Customization is the single biggest opportunity for improving the WordPress experience, and I wanted to know, could you expand on this? And how important is the Customizer in this regard?
The Customizer is everything.
Yeah. You know, I think that the Customizer is definitely, like if I think about leading a release, I could see the Customizer being a main focus of it. You know? That, it’s so important to the user experience of someone new to WordPress especially, but also to everyone who uses WordPress day to day, and it’s also probably our weakest area to be honest. I mean, it’s had a ton of work, it’s so much better than it was, but if you just look at like we’re only as strong as our weakest link, and right now I think our weakest link in user experience is the customization—it’s not just the Customizer it’s also themes—but the customization of the frontend of someone’s site.
