Ask HN: What's the best WYSIWYG CMS for a Rails app?

What do you guys use for editing the marketing content for your Rails apps? I'm looking for a WYSIWYG CMS because editing copy in code is too much of a pain and so I never get it done.

DHH recommended Brochure, which is just a static site generator with erb templates. I've googled around a bit and found Refinery to be the most recommended choice. I haven't tried it yet, because I wanted to get some recommendations from people here.

I'm sure a lot of you have had this problem. So, any thoughts on how you deal with it would be very helpful.

Oddly enough, I find A/B testing tools like VWO and Optimizely to be great for quick content editing even if I'm not really running an A/B test.
