All websites that do what you listed die around 5 years after being made, followed by a few years of resurfacing to the people that finally tried them out. There are none left that are not dead. Myspace was created in August of 2003, so after a decade, it's close to dead.
Facebook will be a decade old in February 2014, so it should be as dead as MySpace by then. Like I said, everything else is old and long been deceased. Now, it's all about apps for tablets because you're more connected to people, (by video and/or pictures).
Stuff like Instagram, Kik, Tumblr, VINE, ooVoo, Skype, etc, etc. I personally use Vine the most. It's hilarious.
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.
