Because Internet: Understanding the New Rules of Language

As a Full Internet Person with Pre-Internet People for parents, this book explained so much about our differences in communication styles. I also loved the discussion of emoji and memes, and the last chapter's extended metaphor about language as a collaborative project as opposed to something static and unchanging. I'm a former prescriptivist/grammar snob who still has to fight that tendency, but I think reframing language in this way will help a lot.

(Disclosure: the author and I are Internet People who follow each other on Twitter, and I was at the meetup/hangout where she was embroidering the piece mentioned in the meme chapter.)
