It's probably more an effort to practice rationality than refine it. Finding good media to entertain, and possibly bring new ideas is (at least) fun. And it's better to take the word of people who already know the quality of something than to spend too much effort or wasting time on things you end up not enjoying.
There was a recent discussion considering the idea of a monthly Book (later expanded to movies, links, etc) thread. The poll was pretty unanimous that this was A Good Idea (tm), so let's give it a try!
Post what you're reading or watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing!
I encourage minimal down-voting in the comments here, because this is a thread for sharing subjective experiences, and I would like people to feel comfortable posting their personal opinion without fearing a karma backlash. If you disagree with a person's recommendation, respond with a comment instead.
I think this is a post that lends itself to comment trees, so I will start one with the categories: Books, Movies, Other, and Meta.
I am interested in hearing if you all think it's a good idea to separate out fiction and non-fiction. (So that the Book thread doesn't have Discworld next to Influence, for example. Or so the movie thread doesn't have documentaries interspersed with rom-coms or what-not)
Poster's Note: Wheee! I made my first working link on the discussion post writing interface! I can learn stuffs!
