As I am more of a back end developer, I've written several interfaces using display:table and then the front end developers cleaned it up into "proper" css. This actually worked out as a good separation of duties and sped up development overall. The programmer in me then asks why this human step is needed if the output is equivalent..
I'm thinking that css is largely about encoding semantic data into layouts, because as far as I can tell it takes tremendously longer to do anything in css today than it did with tables in the 90s. And doing things in tables took tremendously longer than using a GUI like Adobe PageMaker in the 80s. We keep going backwards in productivity but there must be some value in the minimalism of how data is described and organized today.
