StumbleUpon is fun, and you can make a mini-blog... I've never had much luck with Tumblr... Blogger is fun for 3 days... google plus is great and like a micro blog but if you really want a blog that you can easily convert into a website or vice versa, you could use WordPress, Joomla, or Drupal. I'd recommend WordPress or Joomla unless you're a programmer, which case you could use Drupal. If you have no money or hosting you can use Weebly, which is free, but comes with ads, but is easy for making webpages.
For WordPress and those other sites try http://www.bluehost.com/track/fiddydips/... for 1 click install. This come from experience, because I've tried half a dozen other hosting companies and I've never really had service like this. It's fantastic.
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.
