Today on Facebook, author Nat Russo shared a link to an infographic showing the uses of various punctuation marks, ranked in order of difficulty based on how many uses each mark has (and thus how difficult it is to learn all those uses, I suppose). Unsurprisingly, the comma is listed in that infographic as the most difficult. I don’t quite understand why (yes, commas have many uses, but they’re straightforward), but I have done enough proofreading of others’ writing to know that this is the punctuation mark that gives most people trouble. (On the other hand, when reading an article about why Ann Coulter hates soccer, I saw some serious semicolon misuse. Those are only for separating items in a list if some of the items themselves contain commas; otherwise, stick with commas. *shakes head, mutters something about journalists*)
Anyway. Infographic. Uses of 15 punctuation marks. Plus a link to a printable download of the infographic to hang over the desk for quick reference. Good stuff for warding off the Red Pen of Doom.
