After an assignment of reading “Eats, Shoots and Leaves,” I challenged my students to come up with new punctuation marks that would fill in the areas not covered by commas, colons and semi-colons. Not surprisingly, suggestions focused on how to make text messages and e-mail messages more clear. One of the best today came from Lyndsay Nystrom, who suggested a way to indicate more letters in a word to help denote sarcasm. Her example:Riiiiiiight. The idea: Use exponents. Ri^9ght. Hmmm. ( Or should that be Hm^2). Maybe this needs a little work. I need to find exponents on this dashboard.
