If your statement is that we should cultivate explicit speech on LessWrong, then I would agree that the members of this community already practice that norm, and advocating it here is appropriate.

If your statement is that we, as members of the LessWrong community, should spread the use of explicit speech to the masses, then I would disagree, as training people in even small ways like that takes significantly more time than is worth the effort except with very close friends.

Or did you mean something else? You really should be more explicit ;-P
