Static engines: * Do one thing _good_ (i.e. blog) * Fewer lines of code, which means: * Easier to maintain * Easier to read * Easier to customize using small chunks of raw code Dynamic engines: * Do many things (i.e. having multiple authors, multiple formats, visual editors, plugins, etc.) * Many more (as in x^5) lines of code, which means: * * Harder to maintain * * Easier to use for _non programmers_ * * Easy to customize SOME things (apply a theme), HARD to customize the whole thing properly (you need to read huge chunks of code that might break if you change them) -- The above reasons make Wordpress pretty much insecure compared to a Static website (i.e. Jekyll engine like octopress). Of course you could have a bloated wordpress websites where all it's plugins are revised and secure while you could have a static website where it's running buggy JavaScript which reveals your IP to the NSA (random example pick) but the % of having a bug in a bigger (in terms of lines of code) app is way higher.
