I'm currently making a dynamic rewrite of a legacy CMS written to generate static files. The static CMS is a huge PITA. Yeah you can slip dynamic features in there 'just' where you need them. What you wind up with is a mess, and once your site gets a lot of content you start generating a LOT of files. Our rebuild process can take a couple hours, and while it does that it's pegging the disk. There's nothing wrong with static sites, for something like a blog it's OK. The feature set is fairly limited. But once you do want to add dynamic stuff, it can get tricky. I'd say for most projects starting with a static generator is a mistake because unless you know for sure the requirements won't change you can easily paint yourself into a corner.
