The reason why Weibo limited the number of words was to ensure the quality of the content and avoid it being difficult to express ideas because of too many words. Weibo is a social media platform that aims to provide users with fast, concise, and light content, so it has a word limit. Although Weibo limited the number of words, users could increase the length and variety of content by setting the text format, using emojis, inserting pictures, and so on. In addition, Weibo also provided some word counting tools to help users better control the length of the content. For Weibo, although the number of words was limited, increasing the length and variety of content in a variety of ways could better meet the needs of users and improve the user experience of the platform.
