I'm not usually a fan of this site, but the "irony mark" and "certitude point" are rather appealing to me. I'm not going to tell you what part of my oral comps preparation led me to this discovery. I'll let you create a story. It would probably be better than the real story!
Although, the use of the "irony mark" seems to defeat the actual use of irony.
(Kik - Is there any way you could incorporate the use of these marks into your novel? You could be a pioneer! And it would be Ah-MAZE-ing!!!! Just a thought.)
