One great thing about these static file generators is that they make it easier to preserve history.

You can't just leave Wordpress based blog to linger on your server after you have quit blogging. It will occasionally eat all your resources and every once in a while new gaping security holes are found which need to be patched. And if you decide to switch hosting provider, it's a hassle.

With static files all these problems go away and maybe our kids get to see what daddy wrote 30 years ago.
