Okay, I'm late to this party, but I'm very interested in this issue, as I have plans to write a book that would be licensed under something like GFDL or CC by-sa.

To help myself understand this stuff, I imagined that I had written my great book and that someone now wants to use its content. What sorts of uses do I want to allow, and what things do I want to prevent? My book would be a regular sort of math book, and perhaps someone else writing a book would want to include one of the chapters from my book. The GFDL would require "Transparent" copies and copies of the full license, which seems a bit annoying; if my book was licensed CC by-sa, someone could put one of my chapters into their own book or whatever and simply include a couple little statements of source, authorship and license; only a few inconspicuous sentences would be required. I think I would be very happy if I wrote my book and someone else wanted to include a version of one of the chapters into their own work, even if that work otherwise used ordinary copyright, and if readers of the new book didn't have access to "Transparent" copies, or if they had to visit creativecommons.org to see the license. So in this one instance, the CC license strikes me as better than GFDL. Dan -- --- Dan Drake ----- http://mathsci.kaist.ac.kr/~drake -------
