Hey all: we build a ton of websites in Craft and I've presented technical topics at their yearly conferences before. Happy to answer any technical or other questions about Craft here or via email, if anyone is curious to learn more.
In my opinion it's a great CMS and a good choice for the W3C site. It's content author-friendly, is also very developer-friendly and supports modern development/SDLC processes. You'll be pleasantly surprised if your only PHP-based CMS experience is with other CMSes.
It’s been good for our clients! WYSIWYG is a required feature for many of them and I’ve found Redactor better than a lot of alternatives we’ve tried. What issues do you have?
One thing that’s helped us is making heavy use of Craft’s matrix blocks. That keeps a lot of styling and inline elements out of the WYSIWYG itself. Then we can turn off a lot of the WYSIWYG buttons/features and keep it simple.
