Vimeo is definitely worth the price, but you do not need to have a premium account to upload HD videos! Also youtube allows HD uploads. In my experience, Vimeo has the best quality.
Another free option which I think is better than youtube is Blip.tv.
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.
