Although chatting online can help people maintain social connections, there are also some disadvantages. 1. Online chatting may make people addicted to the virtual world and lose social activities in the real world. Online chatting can also lead to personal privacy leakage, especially those who chat anonymously. 3. Online chatting may also lead to excessive use of electronic devices that affect one's health. Online chatting may also affect people's judgment and thinking ability, especially when dealing with complex problems. Chatting online may also waste time and make people miss other important things such as work, study or family activities.
