As far as I know no one has built anything more complex than a class browser. I would say Spec was incapable of building a complex interface of any kind. It's clumsy, developer-hostile, and counter- intuitive.
The whole Spec process of writing code in three different places is the very definition of a /super pain in the asset/s. it is far less intuitive to my mind than creating composite morphs.
Progress on Spec is glacially slow - but that's not the problem. Spec is profoundly misconceived and fundamentally flawed and offers nothing over raw Morphic. The Spec model is simply not how anyone would want to build an interface in 2014. I certainly would never use it.
Okay, but how do you really feel? :) I'm intrigued by the 2014 comment, though (which of course will look hilarious in 2015). How do people want to build interfaces in 2014? -C -- Craig Latta netjam.org +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)
