For those who still question the useful of social media sites

Social media allows you to connect with others but these sites are about more than letting you know what your friend is having for breakfast. They give us a forum to share knowledge with each other and unlike the past it is knowledge that you want. You seek out this knowledge by subscribing to someone who posts what you want to know about and if you don't like it you can easily unsubscribe anytime. Following people has increased my world view, introduced me to new topics, allowed me to keep in touch with friends and family all over the world, keep abreast of current news, the benefits go on and on. So if you want to keep learning subscribe to others today, who knows what you'll find.
