I'm writing an attempt at a RationalFic. So far, I posted about it to /r/rational at Reddit, in an Open Thread here, and I've now finished the first story arc. Since there's a new Media Thread tomorrow, I plan on posting about it there.
What I haven't done is make a separate Discussion post. I kind of want to, in order to generate as much useful feedback and commentary as possible, but I've been told in the past that a few of my Discussion posts should have gone in Open Threads instead.
I suggested recently that part of the problem with with LW was a lock of discussion posts which was caused by people not thinking of much to post about.
When I ask myself "what might be a good topic for a post?", my mind goes blank, but surely not everything that's worth saying that's related to rationality has been said.
So, is there something at the back of your mind which might be interesting? A topic which got some discussion in an open thread that could be worth pursuing?
If you've found anything which helps you generate useable ideas, please comment about it-- or possibly write a post on the subject.
