Well posted Derek, and wholehearted support for smaller, practical increments of openness. There's a healthy dimension of semi-permeability as we grow the infrastructure, business models and cultural space that allows for tinkering, creativity and conversation between otherwise polarised worlds. We need the room to negotiate bridges between the 'hippies' and the 'profit-mongerers' if we're to win the cause for our humanity rather than converting a side.
Some easy-to-try gray areas (sorry) allow for a broader range of invitation points for those sharing works to ease into, safely. It needs no zealotry or freedom-fighting for the cause of openness, it becomes about feedback on what actually works.
BTW the link didn't go in the right direction, herewith again >> Degrees of Openness: PDF
Bless the binary, but bring on the human interface between,
