I certainly like the problem it aims to solve. After playing with it for a bit my only gripe is that it feels a little clunky and hard to use. I wanted to create a sample document, save it and share it as an example in the post. I was bummed when I had to add 10 words or more for a description to save. Then the save button seemed to disappear. I was also bummed when I could only create an account by using a social profile (GitHub was not one of them). For all you Sass lovers out there, one thing I did love was that it seemed like Compass was being included by default.
Needless to say, Yuguang has done a great effort on what I think could be an awesome tool, and it’s even better that he shared his code for us all to learn from as well as contribute to.
