Ive noticed reply tweets (those starting with @something) do not get sent to Facebook. But you don't want to type @fb (does this exist? Surely it must) as that may be confusing you could experiment with just the @ sign alone or perhaps @#fb.
Pretty sure one will work. You may also want to experiment with other characters like $, %, & or perhaps unicode characters like the geometric â–º or the Dingbats â¢. I sympathize with not wanting all your tweets going to FB; i'm driving my FB friends crazy.
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.
