2- Don't forget that it is a social website and a lot of people can see your comments, photos, and all you did, see, put the privacity in the mode that you want and you think is the best.

But, also they have positive aspects, you can speak with friends from any part of the world to any part of the world, also you can upload a photo and comment there all the friends to meet somewhere to do something
