If you don't keep up with punctuation news, you may not have heard about the new mark, now being adding to some digital fonts and keyboards. The Interrobang is a question mark overstruck by an exclamation point, the equivalent of ?! It's also the clever name of an online, collaborative problem-solving game developed by Microsoft Partners in Learning in partnership with Learn & Serve America and the Smithsonian. Students competed in three leagues (EL, MS, HS), "taking on missions that engaged them in real-world problems, from bullying to biodiversity." At this site you can look at the results via a user-friendly display and learn how to get involved in future versions. [Update: a new Interrobang event is now online (Dec. 2010). Check it out.
