This is an incredible gift for WordPress new user experience improvements. And it's honestly painful, but important, to watch and learn from. Thanks to WP Site Care for doing this. You can thank them too, by going to Loopconf, which they organize, and for which we'll be a media partner!
WP Site Care recently did an experiment where they gave users specific tasks to do on three content management systems (WordPress, Wix, and Squarespace) and timed them to see how long it took. Additionally, they have videos of every single session.
