My favorite social network is vkontakte.It is more convenient to use than other social networks. You can upload photos in it. You can also exchange voice messages. "Vkontakte" you can listen to music, collect your own playlist. I like VKontakte because I can communicate with my friends from a distance. You can view photos of friends and acquaintances. You can give virtual gifts for the holidays. You can play various games. There are also mentions that will help you not forget about the birthday of my friends.
