You shouldn't really have to worry about this. But if querying the DB and rendering the page is a performance hit for you (and the data is - mostly - static), then you could start caching either the data or the rendered page itself. Just look into Zend_Cache for an easy, tried-and-tested solution that can handle both of these scenario's.
If you use absolute paths for the images, stylesheets etc it will most probably be cached by browser. Otherwise you can use many of the caching solutions available like memcached. You can also cache images using phpThumb and mod_rewrite as explained here.
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.
