Gretchen McCulloch is a self-described “internet linguist,” host of the podcast Lingthusiasm, and author of the recent book Because Internet: Understanding the New Rules of Language. In it, she demonstrates that the way we've come to speak on the internet -- from emojis to exclamation points -- is not random or arbitrary, but part of a broader attempt to make our written communication more vibrant, meaningful, and, genuinely human. Far from ‘ruining’ the written English language, internet-speak, McCulloch argues, is revolutionizing language in unprecedented, and ultimately positive, ways. We discuss why I feel bad if I don't use enough exclamation points (or use too many), why postcards are the pre-internet predecessors to Instagram, how emojis act as written equivalents of our body language, why sarcasm is like a “linguistic trust fall,” the meaning of “Ok boomer” and much more.
