Facebook allows users to connect with friends and family by posting statuses, sharing photos, videos, music and links. It also features pages that users can follow and see updates from in their newsfeed. Google+ is similar to Facebook with circles to organize friends and the ability to share information within those circles. YouTube is the world's largest video sharing website where users can search, watch, and upload videos. Instagram is a mobile app where users can take pictures, add filters, and share photos with followers.
