There are people who will put up with a relentlessly and honestly rationalist approach to one's friendship or other relationship with them. However, they are rare and precious, and I use the words "put up with" instead of "enjoy and respond in kind" because they do it out of affection, and (possibly, in limited situations) admiration that does not inspire imitation. Not because they are themselves rationalists, reacting rationally to the approach, but because they just want to be friends enough to deal.
I've often had half-finished LW post ideas and crossed them off for a number of reasons, mostly they were too rough or undeveloped and I didn't feel expert enough. Other people might worry their post would be judged harshly, or feel overwhelmed, or worried about topicality, or they just want some community input before adding it.
So: this is a special sort of open thread. Please post your unfinished ideas and sketches for LW posts here as comments, if you would like constructive critique, assistance and checking from people with more expertise, etc. Just pile them in without worrying too much. Ideas can be as short as a single sentence or as long as a finished post. Both subject and presentation are on topic in replies. Bad ideas should be mined for whatever good can be found in them. Good ideas should be poked with challenges to make them stronger. No being nasty!
