No need for attitude, you asked for feedback. That being said:
- You call Barley an editor when in reality its just service, and expensive one at that. - Barley is marketed for developers, but in essence is a closed system that doesn't allow for modification or developers to add new functionality.
Honestly the product looks pretty good the design and available themes are decent and I understand why the concept behind barley can be useful for some people but I think you are targeting the wrong audience; developers like to tinker; barley doesn't seem to be designed to easily do that.
My advice, remarket it as a blogging platform for designers.
