My Life Online

When I think about my life online, the first think witch thing which [better: that] comes to my mind is Facebook. Without a doubt, Facebook is one of the most popular social networks. The main reason why I use Facebook is the number of users. Nearly everyone uses Facebook. I use it to keep in touch with friends of mine, whom I can’t talk to [in person?] or who are too far away to just drop by. Facebook is also handy to for sending messages and sharing pictures or to just get to know what is happening around the world.
Another useful social network is Skype. With Skype you can do make voice calls and write messages. You also can also do that with Facebook, but the quality of Skype is much better and you don’t have to share so much many personal details with people you probably don’t know. I mainly use Skype to talk to “friends” from foreign countries who I don’t know personally.
There also many other social media sites I use e.g. Instagram, to share pictures of my everyday life, Youtube, to watch video clips, or Whatsapp, to send free messages to my friends. [Free massages by Whatsapp would be nice :-)]
