Wordpress is the most popular for its ease of use and functionality. Drupal and and Joomla give a lot more functionality, but they are not anywhere near as easy to use. Having the massive support network that Wordpress offers makes a big difference.
I chose Wordpress for what it can do and the amount of people that use it - there are plenty of people that you can ask for help when something goes wrong.
For ease of use, speed to design, and scalability I've found that Squarespace is by and far the better choice. You can quickly get a site up and running with little knowledge of configuring a web server, writing html, css, etc. Plus Wordpress is a headache with the security updates and vulnerabilities that have left other bloggers burned, with SquareSpace this is all transparent to 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.
