BTW, if I read your reply here Andrew, you are suggesting I'm being a pain in the ass to insist that the original terms I released my content under (the GFDL) is something that can't be casually dismissed by a community vote of some sort. I can't speak for "most people", but I can speak for myself. I want to not only preserve the ability to make my contributions freely available, but I also want to maintain the current philosphy of the GPL/GFDL that prohibits others from preventing future distribution, or asserting copyright on content they haven't written.
I only used "pain in the ass" here because you had said it yourself in the message I replied to (although you more politely used the PITA acronym). I certainly am not implying that you are being a PITA here. My point with the question was that the specific case of CC-BY-SA is a very nice analog for the GFDL in many respects. The Share-alike (SA) requirement of the license ensures that it is perpetually viral like the GFDL is, and the By-attribution (BY) aspect ensures that authors receive proper credit for their work. From a philosophical standpoint, this is almost identical to the GFDL. The benefit to using CC-BY-SA over the GFDL is that CC-BY-SA documents do not need to be accompanied by the whole text of the license, which is a gigantic benefit for short documents and images. This is why wikinews chose to switch to the CC-BY-SA, why commons prefers that license for it's images, and why many wikibookians are interested in per-book cross-licensing arrangements with this license.
In short, my question is this: considering that the basic rights and protections are the same for both licenses, and they differ primarily in the way in which they are enforced, does it really matter to you, the content creator, whether we use one or the other? Either way, you are the author receive proper attribution and the assurance that your work will be perpetually available to other for free under the same license. Enforcement has much more to do with WMF as a content host, and the various content consumers then it has to do with the authors of the content anyway.
