what does it mean?
some thoughts on openness:

open systems are free to be redesigned by their users. this leads to a 
worthwhile benefit, which is that open objects will work together 
cooperatively as functioning systems with a minimum of ugly hacks and 
"adapter" layers.

open systems are designed for designers, so the pieces should be 
reusable in other projects with a minimum of waste.
