Depends on how important the word is. Like in a Written Role-Playing Story (or RP), sometimes a single word changes everything.

It doesn't come down to how little or how much a post has in terms of words, it comes down to how meaningful the post is. If the post is meaningless but has a ten-page essay, it is no different (it temrs of how meaningful it is) as a post that is one word.

This especailly is true with "question words" (who, what, why, etc.). Like if you qoute a post and put "Why?" that post is meaningful, though not elobortory.

Thus, I do not mind if the post is one word as long as it is meaningful.
