I think the elipsis is the most underrated grammatical tool. How much meaning is conveyed in a million different circumstances? Someone types something stupid, i type “ok…..” so that it perfectly conveyes the way you say ok in conversation as if youre waiting for the person to finish the thought. In real life it makes the person feel self-Conscious and the train of dots in an IM window or a forum thread does the same thing on a relative scale. It can also convey thought like “we’ll see……” and the person reading gets the sense that i am putting thought into whatever it was we were talking about regardless of whether or not i actually am. It is so useful i heart the elipsis.
