Whatsapp is the best social networking site that I have ever used. I am using WhatsApp from last 3 years. It is the best app to get connected with your friends. It provides a service of sending free text messages to friends as well as relatives. Now whatsapp also have launched a new feature with the help of which you can upload your stories in the format of photos or small videos and share your feelings with your loved ones. You can also create groups on the WhatsApp and chat with all your friends in the group. I use WhatsApp for many other tasks such as group discussion, group studies, etc. It is the very good platform for increasing knowledge enormously. However due to use of WhatsApp people especially youth are avoiding face to face meetings and are getting more lazy. Thats the main drawback of the WhatsApp. Also it doesnt have some other special features that other social networking sites have such as photo editing and stickers for the photos. Besides this WhatsApp is the best social networking site.
