I think a recommended literature enhancement would be very cool. The topic of each post would always be the name of the publication and its and author(s), and the poster would remain anonymous. Anyone could post, and no points would be awarded to the poster. A thumbs up or thumbs down would mean "liked it/relevant", "didn't like it/irrelevant". Again, no points awarded or taken from the poster.

Comments would be divided into 2 groups. One group would be for recommendations by folks who have read it to folks who have not (non-spoilers). The second group would be for those that have read it and would like to discuss it.

Points would be awarded as normal in both groups.
