Pros: Only the ones you know and the users you've approved will see your tweet. Cons: What's the sense of having your Twitter account if you'll just keep it to yourself and to some people? The use of Twitter is to put in your status so everyone could see it.
If you're going to protect your own tweets, then don't bother creating your account. There's no sense on following a certain person with protected tweets since that person must approve you first if you'll be allowed to see his/her status or not. You can send someone a message if you've given her a privilege to see your status... if not, then he/she won't see it anyway unless you'll send a direct message to that person (if in case he/she is following you).
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.
