This document discusses how Facebook has become the new standard for social interaction and maintaining connections with others. It contrasts socializing before Facebook, when people would call or instant message others to make plans, with the present where people use Facebook to stay in regular contact with acquaintances from long ago and see constant updates about others' lives. Now, through Facebook, people can publicly share details about their daily activities and social events through status updates and photos, and others can easily engage by liking posts and reminiscing about past memories shared on the site. Facebook has fundamentally changed how social lives are structured and maintained in modern times.
