Final answer:
Readers expect to quickly understand the main point of a routine business message, as brevity and clarity are essential in today's fast-paced communication environment.
Step-by-step explanation:
Most readers expect to grasp the main point of a routine business message relatively quickly. In an era where social media dominates and attention spans are short, it's crucial that the communication is crafted to be clear and succinct. A quick perusal should reveal the essentials of the message, much like a "30-second sound bite." Experts note that viewer attention on social media can start to drop significantly after just one minute. Likewise, in a business context, readers prefer emails with short, to-the-point paragraphs. Effective business communication should allow readers to understand the main point without requiring extensive reading time.
