I suspect that rationalist Homestuck fanfiction would be interesting and received fairly well (assuming it's noticed, which is unlikely). That said, I don't consider myself equal to such a task.
The thought's crossed my mind before. I think there's scope for implicitly rationalist fanfic there, given the characters' powers and interests, but explicitly rationalist would be difficult to pull off; the story's strength lies in characterization, and bringing anyone too far out of character to make a point would be poorly received. In particular, you couldn't get away with tweaking the viewpoint character the way Eliezer and Alicorn have in their respective universes.
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!
