Thanks for the kind words, everyone! I'll try to answer some of the questions that have arisen.
With respect to the CC license, I'm not a lawyer, nor have I consulted with a lawyer or WotC about this. As far as I can tell, it's a pretty straightforward interpretation and response to section 10.2, "Third Party IP", of the GSL.
It's not related to the release date issue. But it is a free / promotional product, which is related to the release date issue, as per section 5.4. I wouldn't characterize this as a loophole or an exploit or anything -- it seems clear to me that WotC intends for people to release free stuff prior to October 1st (but after their 14-day wait period.)
On a different topic, Knowledge (Current Events) was released pretty irregularly even at the best of times, but it's still at least theoretically possible that some news story will grab my jugular and refuse to let go.
On a different different note, I feel it's a bit... self-serving, I guess, to 'submit a scoop' on my own stuff. But I certainly wouldn't be adverse to folks out in the audience thinking it was scoop-worthy and acting accordingly.
Thanks again to everyone who has taken a look at this.
Cheers,
Roger
