I think this is silly, and it's a hill I'm willing to die on. I wrote this in a comment yesterday, and Jeff has fully confirmed/vindicated this in his post: SSGs are good for static sites with no interactivity or feedback. If you want interactivity or feedback, someone (you or a 3rd party service provider) is going to have to run a server. If you're running a server anyway, it seems trivial to serve content dynamical…
The code surface with SSG + 1 or 2 small self-hosted OSS tools is much, much smaller than it ever was running Drupal or another CMS.
