My 60 yr old mother runs 2 small nonprofits, and is responsible for the web content and design. She's a pro with Word Perfect, but gets confused by simple HTML tags, and no interest, time, or aptitude to learn HTML/CSS/JavaScript. Last weekend, she asked for help with her website, and I was shocked to find out they still look like they're out of the late 90's. She does all of her editing with a 2006 copy of dreamweav…
We're launching in about a month. Basically, we're a static site generator with a CMS. You don't even use YAML or front-matter. Just build your forms with a local GUI, then pass yoursite.com/cms/ over to your Mom so she can edit in a wysiwyg (or markdown...whatever). Design with normal css/html and Django style templating.
I built it because I loved static site generators (some great tools in that list), but they were all worthless for me as soon as I needed to pass the site off to non-hacker friends. I wanted it to be easy on me and easy on them. Using firebase and ember, we were able to load the entire CMS off a static server (we still need a server to regenerate on changes though).
And before you ask, yes we're trying to figure out how to make it self-hostable. It's a little harder for us, since we use a bunch of separate services (firebase, elastic search, google image resizing...etc) to make it so you don't need to install much locally, just Node. Small team at the moment, trying to avoid VC investment and went straight to Kickstarter.
For everyone else who just likes SSGs and don't need a CMS, I'm a big fan of Harp and Cactus. The later because I came from a Django background.
