Facebook is a popular social-networking site(and app) where users connect with people of their choosing - either privately or publicly - and post pictures, text, or videos. Users also can play games, watch videos, decorate their pages, post and tag photos, share favorite product information, "like" favorite celebrities and social causes, live-stream video with Facebook Live, connect with goods and services, and live-chat via Messenger, an app that is integrated with Facebook. Though the app itself doesn’t generate iffy content(beyond underwear ads), users create plenty, so the content in a teen’s feed is dependent on friends, facebook is very diffrent to other social site so please enjoy.
