twiller
n.— «Recently, a handful of creators (present company included) have scrapped pen and paper for mobile phone and keypad, and started texting their novels—in real time, just a few characters at a time. Our medium is Twitter, a service that lets you broadcast bursts of 140 characters at a time to be read by people who subscribe to get your updates. In my case, I’ve for the last two months been using Twitter to write a real-time thriller. Hence: Twiller. (Cheap word play is what you get when you disintermediate, as they say, your agent and editor).» —“Introducing the Twiller” by Matt Richtel New York Times Aug. 29, 2008.
