The article discusses the issue with using relative dates such as 'yesterday' or 'a week ago' on websites, as they can be misleading and unclear. The author argues that these labels pretend to speak human language but actually don't, as humans understand 'yesterday' to mean the day before, not just any time within the last 24 hours. The article suggests that using specific dates would be more accurate and helpful. The author believes that using relative dates can lead to a lack of trust and make the information less useful.
