The writer Emma Straub has 9,192 Twitter followers. That might seem like a lot for an author whose first novel, Laura Lamont’s Life in Pictures, hasn’t even come out yet. But Emma Straub is really good at Twitter. She’s funny and charming and evinces great enthusiasm for the books and stories of the fellow authors and critics in her social sphere. Outside of Twitter, Straub writes for many bookish publications, she’s the daughter of the novelist Peter Straub, and she runs a small design outfit with her husband that’s made posters for everyone from Passion Pit to Jonathan Lethem.
