There's a risk that any amount of thinking about infrastructure could kill off what energy there is, and since there appears to be some energy at present, I would rather favor having the discussion about the book club in the book club thread. :)

IOW we can kick off the initiative locally and let it find a new venue if and when that becomes necessary. There also seems to be some sort of provisional consensus that it's not quite time yet to fragment the LW readership : the LW subreddit doesn't seem to have panned out.

It seems to me that Jaynes is definitely topical for LW, I wouldn't worry about discussions among people studying it becoming annoying to the rest of the community. There are many, many gems pertaining to rationality in each of the chapters I've read so far.
