I just came across Serenity (http://serenity.is) and it looks very promising.

I am usually either working alone or with one other dev and this looks like it could save a lot of time on face value.

I am always dubious of this like this as have been burnt in the past with similar things that I spent a lot of time learning to then realise were actually flawed in design.

Does anyone have experience with this framework? Would you recommend it? What is the learning curve like?
