"Ted the two I looked at most closely were medium.js and Dante. http://jakiestfu.github.io/Med... https://github.com/michelson/D... The genre of editor that makes the most sense is one that's trying to mirror the Medium feature set. That's what both these editors aim to do. It looks like Dante is the more complete of the two. But there are other drop-in editors written in JavaScript. I wanted to cast a net as wide as possible to see what would come back. This is a decision lots of other people have had to make. For example, what does Ghost use? They had the same decision, though a while ago." - Dave Winer
