Which of the following is considered a rule of netiquette?

Proofreading written communication before sending is a vital rule of netiquette because it ensures clarity and professionalism in digital interactions. Proper grammar, spelling, and punctuation contribute to the effectiveness of your message. When communication is clear and free of errors, it reflects respect for the recipient, enhances understanding, and minimizes the chances of misinterpretation. This practice is especially important in professional and formal settings where the intention is to convey information accurately and respectfully.

In contrast, using all capital letters can come across as shouting and is generally viewed as rude. Sending emails at late hours may not consider the recipient's time and could be perceived negatively. Jargon and slang, while appropriate in casual contexts, can create confusion in more formal communications, alienating recipients who may not be familiar with the terms used. Hence, proofreading stands out as a rule of netiquette that promotes effective and respectful communication.
