IAWYC, modulo the use of "should": at least with connotations assumed on Less Wrong, it isn't associated with compulsion or emotional load, it merely denotes preference. "Ought" would be closer.

It's true that in technical contexts "should" has less emotional connotation; however even in say, standards documents, one capitalizes SHOULD and MUST to highlight the technical, rather than colloquial sense of these words. Banishing them from one's personal vocabulary greatly reduces suffering, and is the central theme of "The Work" of Byron Katie (who teaches a simple 4-question model for turning "shoulds" into facts and felt-preferences).

Among a community of rationalists striving for better communication, it would be helpful to either taboo the words or create alternatives. As it is, a lot of "shoulds" get thrown around here without reference to what goal or preference the shoulds are supposed to serve.

"One should X" conveys no information about what positive or negative consequences are being asserted to stem from doing or not-doing X -- and that's precisely the sort of information that we would like to have if we are to understand each other.
