Facebook is a popular social-networking site(and app) where users connect with people of their choosing 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 I think Facebook should change some of its features like tag all friends with only one click, should introduce’dislike’ option, and stop all Candy Crush requests. Most of the time we view others profile. If we find the way how to check who is secretly viewing our profiles that would be really great.
