I like how easy it is to make things look nice with this framework, as well that you don't have too many files if your project gets bigger than just one page or two pages of content (which makes sense).
It's also pretty fast because there are no external libraries involved in its development which helps speed up loading times quite significantly! Nothing really - but then again nothing bad either ;-) But what has been good about using ampsandoJS so far was being able create simple applications without any problems at all since they were very small/simple projects compared other frameworks out their such jQuery etc; And most importantly i can now use my own stylesheet instead adding another library every time when creating new webpages :).
