They aren't all exactly the same... If you're asking what site is best for social communication, I'd say: 1. Facebook 2. Twitter 3.
Myspace 4. Google.
MySpace is definitely not one of them so you can take that off of your list. Google+ is pretty much a ghost town and Twitter can be too complex. Facebook is the easiest and one of the most populated social networks now.
So in my opinions it would be facebook.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
