Tweetie is considered to be the best but many people also like Tweetdeck, especialy if they use Tweetdeck on the desktop. Mashable has a nice comparison. mashable.com/2009/06/16/tweetdeck-vs-twe....
Tweetdeck is by far the best free app. It gives you the most options, and it syncs with the desktop version, so you can have all your custom columns with keyword searches, DMs, replies, or friend groups. Twittelator Pro is also really good, but you have to pay for it.
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.
