I have been using facebook for few years now and it is one of the good social networking site where you can connect with anyone in the world. This social networking giant has made its users addicted to it by its features. If you have an email id you can create an fb account and registration process is easy and at a free of cost.
You can create groups for schools, college and work. You can connect with the friends and their friends and you can able to post a video, like, comment of others post. This is most widely used communication website now. We can also make free video calls to anyone in the friends circle.
