In order to understand the importance of language in design, particularly in messaging apps, it's essential to recognize that every element, including words, must pull its own weight. A simple design relies on these elements working together seamlessly. The Intercom Messenger interface experienced intense reactions to minute details of grammar and phrasing, demonstrating how expectations play a significant role in conversation evolution. This highlights the need for clarity in understanding who's speaking at all times. By giving stage directions, such as messages from Intercom that provide instructions and context, designers can help human participants know what's going on and act accordingly. The importance of pronouns and adverbs cannot be overstated, as they manage time expectations and convey a message's intended meaning. A crucial lesson learned is the need to focus on one job at a time, setting aside competing demands and ensuring clarity in communication. Tiny changes have significant impacts, and designers must sweat the details to push their designs forward while maintaining simplicity. Ultimately, understanding language and its role in design can significantly influence how users perceive products and expectations around them.
