As most people who spend a significant amount of time online can likely attest, there are many different text-based ways to express laughter on the internet. Ever wonder which type of laugh is the most common, or if your preferred internet laugh really means what you think it does? Laughing On Line, an interactive visual essay published by The Pudding in October 2019, addresses these questions by "tak[ing] a closer look at the usage, evolution, and perception of the digital laugh." In the first section that readers encounter, they are asked "How funny is it?" Those who wish to answer can choose from a variety of internet laughs such as "heh," "sksksk," and the classic "lol," and then use a slider to indicate what they are actually doing when they use that type of laugh. Readers can also view the total responses without answering. The next section graphs how the popularity of "lol" and several other laughs have changed over time since 2009, while the third section digs into the most popular laughs of 2019. Laughing On Line was created by Russell Goldenberg, Kishan Sheth, Caitlyn Ralph, and Jan Diehm.
