(1) linking to ideas in original posts without summarizing the main ideas in your own words and how they apply to the specific context -- as this creates short-cuts in the brain of the reader, if not in the writer
I plan to keep doing this; it saves time.
(2) Use of analogies without formally defining the ideas behind them leads to content not only saying more than it intends to (or more than it strictly should) but also having meta-meanings that are attractive but dangerous because they're not explicit. [edit: "formally" was a poor choice of words, "clearly" is my intended meaning]
Isn't this inherent in using analogies? Are you really saying "Don't use analogies"?
I like analogies. I think they are useful in introducing or explaining an idea, but shouldn't be used as a substitute for the idea.
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!
