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.
It seems to me that sometimes my ability to do things correlates with weather (high/low pressure), but I don't keep records to prove or disprove this hypothesis. Just writing it here as an example for a hypothesis I would usually not think about. It doesn't explain why person X is more productive than person Y, but it could explain why person Y failed on a specific day.
