Social networking involves building social relationships online through platforms that allow sharing interests and activities. It has greatly affected leisure time as many people log in daily to interact with friends and family. Major social networks like Facebook allow worldwide connectivity, helping people connect, seek advice, jobs, and share feelings and information that spreads quickly. However, social networking can also waste time through distraction and addiction. It risks cyberbullying, reduces real human contact, and can weaken communication skills and grammar through excessive use of abbreviations. Users should take precautions like avoiding oversharing personal details.
