Development of Creative Commons licenses

[Rob Myers <robmyers AT mac.com>]

In an ideal world, all software would be GPL and all content would be 
CC-SA . But "weaker" licenses can be a useful stepping stone as well as 
addressing other contemporary social concerns.

To support this argument (that soft licenses encourage people to try 
hard licenses :-) ), I'd cite this page: http://craphound.com/down/

"I chose the most restrictive CC license available to me, staying 
cautious, and I waited to see if the sky would fall.
...
 It didn't.
...
So here we are, just a little over a year later
...
 I am re-licensing Down and Out in the Magic Kingdom, effective today, 
under the terms of one of the least restrictive Creative Commons 
licenses, the Attribution-NonCommercial-ShareAlike license..."

If it was a choice of all or nothing rather than trying a little, 
finding it works and then going all the way, would this work now be in 
the commons?
