Parents need to know that Facebook is a popular social-networking site (and app -- our review references key points relevant to both) where users connect with people of their choosing -- either privately or publicly -- and post pictures, text, or videos. Users also can watch videos, 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's integrated with Facebook. If users choose, they can hide the "like" count on their posts. Budding game developers may also appreciate the chance to express themselves and share their creations through Facebook's downloadable gaming platform and/or the gaming section of the site. Like the Reels feature in Instagram, Reels on Facebook allows users to create TikTok-style videos that are 30 seconds long.
