All signs suggest punctuation is in flux. In particular, our signs that mark grammatical (and sometimes semantic) distinctions are waning, while those denoting tone and voice are waxing. Furthermore, signs with a slim graphical profile (the apostrophe and comma, especially) are having a rough go of it. Compared to the smiley face or even the question mark, they’re too visually quiet for most casual writers to notice or remember, even (or especially) on our high-def screens.
