From the Kirbyverse

"So yes, as you might have noticed by now, I am a big fan of Kirby, especially because it allows you to solve common problems in a straightforward way, making my life as a designer and developer so much easier, but also because my clients have always been very happy with the content editing experience in the backend – without exception. Kirby enables successful projects." (from Starting A New Kirby Project)
