I am not sure I agree with your second concern. Sometimes premature formalization can take us further off track than leaving things with intuitively accessible handles for thinking about them.
Formalizing things, at its best, helps reveal the hidden assumptions we didn't know we were making, but at its worst, it hard-codes some simplifying assumptions into the way we start talking and thinking about the topic at hand. For instance, as soon as we start to formalize sentences of the form "If P, then Q" as material implication, we adopt an analysis of conditionals that straightjackets them into the role of an extensional (truth-functional) semantics. It is not uncommon for someone who just took introductory logic train themselves into forcing natural language into this mold, rather than evaluating the adequacy of the formalism for explaining natural language.
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!
