I would vote for Facebook its a social-networking place where you can "Add friends" who are known to you via email, even new ones through various groups, share photos, pages, music and chat, all in one place. Twitter is where you post your updates otherwise called “tweets” on your page where friends who “follow” you can view them and you can view the posts posted the same way by whom you "follow" Instagram is where you instantly upload your photos, tag friends in them, like photos, post comments, there are choices of making a photo "public" or customized Tumblr is meant for blogging where you can post text, images, videos, links, quotes and audio to your tumblelog, with private blogs and dashboards.
I'd say Tumblr because um it's the only one I have out of all of these. Basically, to me, most of Facebook is trying to make yourself look good to friends and others. At least that is what I see from countless selfies, stat updates etc. On Tumblr it's basically 'blogging' if you can call it that, whatever you want, photography, nature, sciency stuff, fashion and the fandom side of things for example (That's where stuff gets a bit more crazy :)).
Most of the fun on Tumblr is just looking through your dash. Also, you don't have to worry about what other people think, you can be as weird as hell and no ones really going to judge you or care in most cases. It's also hecka addictive.
To me anyway. There is nothing wrong with Facebook, which is primarily on socialising and games, but to me Tumblr is just more fun to me. Uh Twitter is if you really like being witty with words and following celebrities.
Instagram is simply taking photos and sharing it around. Yep, that's the ramblings of yet another internet addict.
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.
