In the beginning, pop culture wiki TV Tropes licensed its content with the Creative Commons Attribution-Share Alike license for free content.
I suppose the morale of the story is, if you contributed to TV Tropes before summer 2012, you should know they're distributing your content under a license that you didn't give them permission to use.
If we did this, it would be bi-directional, with full intergeneration (i.e., people signed into news/nntp.soylentnews.org could post with their own UID). If we go really geeky, we could even do moderation via control messages :-)
NoCem [cm.org] already exists as a way of posting moderation messages
